In a media teleconference that was held by NASA earlier today, agency officials mentioned that the Space Launch System (SLS) rocket for the Artemis 1 mission will roll out to Kennedy Space Center's (KSC) Launch Complex (LC)-39B for a Wet Dress Rehearsal (WDR) on March 17 (which is St. Patrick's Day)!

The mega-Moon rocket—with its mobile launcher riding atop crawler-transporter 2 (shown below)—is set to exit KSC's mammoth Vehicle Assembly Building (VAB) at 6:00 PM, Eastern Daylight Time (3:00 PM, Pacific Daylight Time) for its 4.2 mile-long journey to the pad.

SLS will remain at LC-39B for about a month if the WDR goes according to plan. It will then roll back into the VAB for final installation of its flight termination system, and other remaining pre-launch tasks.

The March timeframe for the WDR effectively rules out April as a launch window during which the Orion Multi-Purpose Crew Vehicle (MPCV) can begin its flight to the Moon, but there will be several opportunities starting in early May and leading through July for the MPCV to embark on its inaugural lunar mission. Here are the dates:

May 7 - 21
June 6 - 16
June 29 - July 12 (with launch attempts standing down during days surrounding the Fourth of July weekend)

This is wonderful news for Artemis supporters and space aficionados in general...and is a welcome respite from the sad reports currently pouring in from the other side of the world. I stand with the people of Ukraine.

Polaris Program will Undertake a Series of Pioneering SpaceX Dragon Missions, Demonstrating New Technologies and Culminating in the First Human Spaceflight on Starship (Press Release)

Led by tech entrepreneur and Inspiration4 commander Jared Isaacman, this program will advance deep space exploration while raising global awareness for St. Jude Children’s Research Hospital®.

LOS ANGELES, CA (February 14, 2022) Today Jared Isaacman, founder and CEO of Shift4 (NYSE: FOUR), announced the Polaris Program, a first-of-its-kind effort to rapidly advance human spaceflight capabilities, while continuing to raise funds and awareness for important causes here on Earth. The program will consist of up to three human spaceflight missions that will demonstrate new technologies, conduct extensive research, and ultimately culminate in the first flight of SpaceX’s Starship with humans on board.

The first mission, Polaris Dawn, is targeted for no earlier than the fourth quarter of this year and will be commanded by Isaacman, an accomplished pilot and astronaut who led Inspiration4, the world’s first all-civilian mission to orbit that helped raise over $240 million for St. Jude Children’s Research Hospital®.

“The Polaris Program is an important step in advancing human space exploration while helping to solve problems through the use of innovative technology here on Earth,” said Isaacman. “On Polaris Dawn, we endeavor to achieve the highest Earth orbit ever flown in addition to conducting the world’s first commercial spacewalk and testing of Starlink laser-based communication. Alongside these important objectives, we will be supporting scientific research to advance both human health interests on Earth and our understanding of human health during future long-duration spaceflights.” Building upon the Inspiration4 mission, Polaris Dawn will continue to raise funds and awareness for St. Jude Children’s Research Hospital®.

THE POLARIS DAWN MISSION

SpaceX’s Falcon 9 rocket will launch the Polaris Dawn mission from Launch Complex 39A at Kennedy Space Center in Florida. Dragon and the Polaris Dawn crew will spend up to five days in orbit, flying higher than any Dragon mission to date and endeavoring to reach the highest Earth orbit ever flown.

While in orbit, SpaceX mission control will carefully monitor Dragon and the crew as they:

– Attempt the first-ever commercial spacewalk with SpaceX-designed extravehicular activity (EVA) spacesuits, upgraded from the current intravehicular (IVA) suit. The development of this suit and the execution of the EVA will be important steps toward a scalable design for spacesuits on future long-duration missions.

- Become the first crew to test Starlink laser-based communications in space, providing valuable data for future space communications systems necessary for human spaceflight to the Moon, Mars, and beyond.

- Conduct scientific research designed to advance both human health on Earth and our understanding of human health during future long-duration spaceflights. This includes, but is not limited to:

-- Using ultrasound to monitor, detect, and quantify venous gas emboli (VGE), contributing to studies on human prevalence to decompression sickness;
-- Gathering data on the radiation environment to better understand how space radiation affects human biological systems;
-- Providing biological samples toward multi-omics analyses for a long-term Biobank; and
-- Research related to Spaceflight Associated Neuro-Ocular Syndrome (SANS), which is a key risk to human health in long-duration spaceflight.

SpaceX and Polaris Dawn will also collaborate with the Translational Research Institute for Space Health (TRISH), BioServe Space Technologies at the University of Colorado Boulder, Space Technologies Lab at Embry Riddle Aeronautical University, Weill Cornell Medicine, Johns Hopkins University Applied Physics Laboratory, the Pacific Northwest National Laboratory, and the U.S. Air Force Academy.

THE POLARIS DAWN CREW

The Polaris Dawn mission has many first-time objectives, so the Polaris Program chose a crew of experts who know each other well and have a foundation of trust they can build upon as they undertake the challenges of this mission. The crew includes:

MISSION COMMANDER, JARED “ROOK” ISAACMAN

In addition to commanding Inspiration4, Isaacman has over 7,000 flight hours of aviation experience, including ratings in multiple experimental and ex-military aircraft. He set speed-around-the-world records in 2008 and 2009, as well as 100 air show performances as a member of the Black Diamond Jet Team, all of which were dedicated to charitable causes. In 2011, Isaacman co-founded what would become the world’s largest private air force, Draken International, to provide realistic adversary training for the United States Department of Defense.

MISSION PILOT, SCOTT “KIDD” POTEET

Poteet is a retired U.S. Air Force Lieutenant Colonel who served 20 years in various roles to include Commander of the 64th Aggressor Squadron, USAF Thunderbird Demonstration Pilot, #4 Slot, USAF Weapons School Graduate, Operational Test and Evaluation Pilot, and F-16 Flight Examiner. Kidd is a command pilot with over 3,200 flying hours in the F-16, A-4, T-38, T-37, T-3 and Alpha jet. He logged over 400 hours of combat time in support of various operations around the world. Following his Air Force career, Kidd served as the Director of Business Development at Draken International as well as the Vice President of Strategy at Shift4 Payments. He most recently served as the Mission Director of Inspiration4.

MISSION SPECIALIST, SARAH GILLIS

Gillis is a Lead Space Operations Engineer at SpaceX, responsible for overseeing the company’s astronaut training program. This includes the development of mission-specific curriculum and training execution for both NASA and commercial astronauts who fly aboard the Dragon spacecraft.

Progress on Testing and Instrumentation Installation Ahead of Artemis I Launch (News Release)

Work continues inside the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida in preparation for the Artemis I wet dress rehearsal test, currently targeted for next month. Teams have been installing the flight termination system on the rocket and working on the first of a two-part test of the system. For safety, all rockets are required to have a flight termination system that the Space Launch Delta 45 can use to terminate the flight if necessary. Once the rocket and spacecraft systems are verified during wet dress rehearsal testing, the 322-foot-tall rocket will roll back into the VAB for final inspections and checkouts, including the second part of the flight termination system test, ahead of returning to the pad for launch.

In addition to work on the flight termination system, the team is installing instrumentation on the twin solid rocket boosters and core stage, as well as instrumentation needed for the wet dress rehearsal rollout. Artemis I is a flight test, and engineers will capture as much data as possible on the performance of all the systems that are part of the Space Launch System (SLS) rocket and the Orion spacecraft as well as the Kennedy ground systems that support the vehicle during rollout, wet dress rehearsal, and launch. Not only will this be the first integrated flight for SLS and Orion, but it will be the first use of many new ground systems. Thousands of sensors and special instruments will monitor the rocket and spacecraft as they make the four-mile journey to Launch Complex 39B next month. The team is also working to inspect and install thermal blankets on the core stage engine section.

Up next, the team plans to power up the Orion spacecraft as part of testing the flight termination system and then close the spacecraft’s hatch after powering it down.

Photo of the Day #2: A Starship in the Morning...

As expected, Elon Musk tweeted a photo of Starship Super Heavy this morning, after SpaceX's mega-Moon rocket was re-stacked at Starbase, Texas, last night! Once NASA's Space Launch System is rolled out to the pad at Kennedy Space Center in Florida (sometime next month for the Artemis 1 wet dress rehearsal, hopefully), then it's safe to say that a new era of giant super heavy-lift launch vehicles will be upon us...

Also, Musk is giving a presentation on Starship later today!

Over the past hour or so, Starship Serial No. 20 (SN20) was slowly hoisted into the air at Starbase, Texas...as the prototype spacecraft will soon be re-mated to her Super Heavy Booster 4 (B4) rocket.

This processing milestone is made possible through two newly-installed arms (nicknamed the 'Mechazilla Chopsticks') attached to the Orbital Launch Tower that will be used to place or remove Starship Super Heavy rockets from the Orbital Launch Table at the pad.

It remains to be seen when the Federal Aviation Administration will grant SpaceX permission to launch Starship Super Heavy on its much-anticipated orbital test flight. But one thing's for sure, just seeing SN20 and BN4 about to become one again gives us our latest glimpse of what's in store for space exploration...crewed and otherwise.

Stay tuned.

NASA Prepares to Join Two Major Parts for Artemis II Core Stage (News Release)

Technicians are preparing to connect two major parts of the Space Launch System (SLS) rocket’s Artemis II core stage. On Jan. 30, technicians moved the largest part of the stage, the 130-foot liquid hydrogen tank to the vertical assembly area at NASA’s Michoud Assembly Facility. Here, it will be prepared for joining with the 66-foot forward assembly.

The forward assembly comprised of the joined forward skirt, intertank, and liquid oxygen tank completed construction and was transported to the final assembly area inside the factory on Jan. 10. Technicians will move the liquid hydrogen tank back to this final assembly where Boeing, the lead core stage contractor, will join the two structures. This will complete construction of most of the core stage that will launch the first crew on the Artemis II mission.

Only the engine section, the fifth piece of the stage, will need to be added to complete the Artemis II core stage. The engine section is one of the most complex parts of the stage. It includes the main propulsion system that connects to the four RS-25 engines that are built by Aerojet Rocketdyne and are assembled and stored at their facility at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. The engines will be the last items installed on the stage. During launch, more than 700,000 gallons of propellant flows from the core stage tanks to the engines that produce more than 2 million pounds of thrust to help launch the SLS rocket.

The core stage serves as the backbone of the rocket, supporting the weight of the payload, upper stage, and Orion crew vehicle, as well as the thrust of its four RS-25 engines and two five-segment solid rocket boosters attached to the engine and intertank sections. The Artemis II mission will help NASA prepare for later Artemis missions that will enable the first woman and first person of color to land on the Moon.

Dark Mode Activated! (News Release)

As NASA prepares to send astronauts to the Moon’s South Pole under Artemis, divers at the Neutral Buoyancy Laboratory (NBL) in Houston are setting the stage for future moonwalk training by simulating lunar lighting conditions.

At the Moon’s South Pole, the Sun will remain no more than a few degrees above the horizon, resulting in extremely long and dark shadows. To prepare astronauts for these challenging lighting conditions, the team at the NBL has begun preliminary evaluations of lunar lighting solutions at the bottom of the 40-foot deep pool.

This testing and evaluation involved turning off all the lights in the facility, installing black curtains on the pool walls to minimize reflections, and using a powerful underwater cinematic lamp, to get the conditions just right ahead of upcoming training for astronauts.
