NASA - Solar Dynamics Observatory (SDO) patch.


March 30, 2022

The Sun emitted a significant solar flare on March 30, 2022, peaking at 1:35 p.m. EST. NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event.


Animation above: NASA’s Solar Dynamics Observatory captured this image of a solar flare – as seen in the bright flash in the top right portion of the image – on March 30, 2022. The image shows a subset of extreme ultraviolet light that highlights the extremely hot material in flares and which is colorized in yellow (AIA 171).

Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts.

This flare is classified as an X-Class flare. X-class denotes the most intense flares, while the number provides more information about its strength. An X2 is twice as intense as an X1, an X3 is three times as intense, etc. More info on how flares are classified can be found here: https://www.swpc.noaa.gov/phenomena/solar-flares-radio-blackouts.

Record-Setting NASA Astronaut, Crewmates Return from Space Station

 







ROSCOSMOS - Soyuz MS-19 Mission patch.


March 30, 2022

After extending the record for the longest single spaceflight in history by an American to 355 days, NASA astronaut Mark Vande Hei returned to Earth on Wednesday, March 30, along with Roscosmos cosmonauts Anton Shkaplerov and Pyotr Dubrov.

Soyuz MS-19 hatch closure

The trio departed the International Space Station at 3:21 a.m. EDT and made a safe, parachute-assisted landing at 7:28 a.m. (5:28 p.m. Kazakhstan time) southeast of the remote town of Dzhezkazgan, Kazakhstan.

"Mark's mission is not only record-breaking, but also paving the way for future human explorers on the Moon, Mars, and beyond," said NASA Administrator Bill Nelson. "Our astronauts make incredible sacrifices in the name of science, exploration, and cutting-edge technology development, not least among them time away from loved ones. NASA and the nation are proud to welcome Mark home and grateful for his incredible contributions throughout his year-long stay on the International Space Station."

Vande Hei’s extended mission will provide researchers the opportunity to observe the effects of long-duration spaceflight on humans as the agency plans to return to the Moon under the Artemis program and prepare for exploration of Mars.

Vande Hei launched April 9, 2021, alongside Russian cosmonauts Oleg Novitskiy and Pyotr Dubrov. His second journey into space of 355 days is the longest single spaceflight by a U.S. astronaut, previously held at 340 days, and gives him a lifetime total of 523 days in space. Dubrov also remained onboard for 355 days on his first spaceflight.

Soyuz MS-19 undocking and departure

Supporting NASA’s goals for future human landings on the Moon, Vande Hei completed approximately 5,680 orbits of the Earth and a journey of more than 150 million miles, roughly the equivalent of 312 trips to the Moon and back. He witnessed the arrival of 15 visiting spacecraft and new modules, and the departure of 14 visiting spacecraft.

Following post-landing medical checks, the crew will return to the recovery staging city in Karaganda, Kazakhstan, aboard Russian helicopters. Vande Hei will board a NASA plane bound for Cologne, Germany, for refueling prior to his return home. Shkaplerov and Dubrov will board a Gagarin Cosmonaut Training Center aircraft to return to their home in Star City, Russia.

Soyuz MS-19 landing

During his record mission, Vande Hei spent many hours on scientific activities aboard the space station, conducting everything from plant research to physical sciences studies.

With the undocking of the Soyuz MS-19 spacecraft with Vande Hei, Shkaplerov, and Dubrov aboard, Expedition 67 officially began aboard the station. NASA astronaut Tom Marshburn recently took over as station commander, and is joined by NASA astronauts Raja Chari and Kayla Barron, ESA (European Space Agency) astronaut Matthias Maurer, and Roscosmos cosmonauts Oleg Artemyev, Denis Matveev, and Sergey Korsakov.

NASA ‘Go’ for Artemis I Wet Dress Rehearsal

 







NASA - Artemis Exploration Mission 1 patch.


March 29, 2022

In a pre-test review on March 28, NASA gave the “go” to proceed with the Artemis I wet dress rehearsal scheduled for April 1-3. The approximately two-day test will run the Artemis I launch team through operations to load propellant into the rocket’s tanks, conduct a full launch countdown, demonstrate the ability to recycle the countdown clock, and also drain the tanks to give them an opportunity to practice the timelines and procedures they will use for launch.

During the rehearsal, controllers will countdown to T-1 minutes and 30 seconds and pause to demonstrate the ability to hold for up to 3 minutes, then resume until 33 seconds before when launch would occur, then pause the countdown. Then they will recycle back to ten minutes before launch and conduct a second terminal countdown to approximately 9.3 seconds before launch, then end the countdown. Sometimes called a “scrub,” launch controllers may decide not to proceed with launch if a technical or weather issue arises during or prior to the countdown. At the end of the test, the team will drain the propellant to demonstrate the procedures that would be used during a launch scrub. After draining the tanks, the team will review the test data before setting an official target launch date.

NASA will provide a live video stream of the rocket and spacecraft at the launch pad beginning at Noon EDT on April 1 on the Kennedy Newsroom YouTube channel. In addition to updates on this blog, NASA also will provide operational updates on the Exploration Ground Systems Twitter account.

SpaceX - Starship Could be Ready for an Orbital Flight in May

 






SpaceX - Starship Orbital Demo (SN-20) patch.


March 29, 2022

SpaceX has enjoyed a lot of wins in the past few years. In addition to successfully glide-testing and landing multiple Starship prototypes, they’ve rolled out its first Super Heavy boosters, test-fired the new Raptor Vacuum engines, and assembled the “Mechazilla” launch tower at Boca Chica, Texas. They also unveiled the first fully-furbished orbital test vehicle (SN20) that was stacked with a first stage booster for the first time on its launch pad (image below).

Starship at Boca Chica launch-pad

Given the prodigious rate of progress, few were surprised when Musk announced that the first orbital flight test could take place as soon as January 2022. Unfortunately, this date had to be pushed back to an environmental assessment and the usual bureaucratic rigmarole. However, Musk recently announced on Twitter that in light of his company’s success with the new Raptor engines, they could be ready to conduct the long-awaited orbital test flight this May.

The tweet was posted on Monday, March 21st, in response to a story by Michael Sheetz, a space reporter with CNBC. Sheetz cited a recent report (by Quilty Analytics) that showed how Russia’s decision to cut ties with the international space industry (in response to sanctions) would affect the U.S. space sector. This report indicates that SpaceX will be “the clear winner” as the absence of Russian launch services means more business will come their way.

Elon Musk on Twitter

According to Sheetz, this is exemplified by the recent announcement that OneWeb – a Starlink competitor – announced that it had terminated its launch agreement with Roscosmos and signed a deal with SpaceX. Musk responded via Twitter and said that he didn’t expect to see a dramatic increase in launch services for his company, which was already launching two-thirds of the world’s satellites.

According to their original plans, said Musk, SpaceX would account for 65% of the market share for launch services. The termination of Russian launch services was likely to increase this to 70%, only slightly higher. He added that this would not affect the development of the Starship, which could be ready for its long-awaited orbital test flight by May (at the earliest). This estimate is largely based on the production of the new Raptor 2 engine.

The Raptor 2 is an updated version of the Raptor 1 and is simpler and more powerful than the original. Production began in December 2021 at SpaceX’s new engine development facility near McGregor, Texas. At the annual Starship Update hosted in February, Musk spoke about the capabilities of the Raptor 2, which included 230 metric tons (510,000 lbs) of thrust at sea level. Based on their current production rates (7 per week as of March), Musk estimates that they will have 39 engines ready by April.

The is enough to equip one Super Heavy booster, which relies on 29 Raptor engines optimized for sea-level, and one Starship, which relies on three sea-level optimized and three vacuum-optimized engines. Add a few weeks to integrate them into the spacecraft, Musk added, and the entire system should be ready to fly by May at the earliest. But knowing Musk’s tendency to provide optimistic timetables, the flight may happen sometime this summer.

According to the flight plan filed with the FAA in May 2021, the orbital test flight will see the fully-stacked Starship and Super Heavy launch together and separate 170 seconds into flight. The booster will then perform a partial return and make a soft splashdown roughly 32 km (20 miles) offshore in the Gulf of Mexico. The Starship will then achieve an altitude of 200 km (~125 mi) above sea level before performing a targeted soft splashdown about 100 km (62 mi) off the coast of the Hawaiian island of Kauai.

If this test flight goes as planned, SpaceX will be ready to embark on its first commercial flights, including a lunar flyby planned for 2023 (the #dearMoon project). As part of NASA’s Artemis Program, the Starship was also selected to land astronauts on the Moon for the first time since the Apollo Era. This will be the Artemis III mission, which is currently scheduled to occur sometime in 2025.

Beyond that, the Starship and Super Heavy launch system are integral to SpaceX’s long-term goal of making regular trips to the Moon and Mars and establishing a permanent human presence there. As always, things may not be happening according to the original timeline. But they are coming together nicely!
