NASA Doesn't Know When Starliner Will Return From Orbit

After helium leaks and thruster problems with Boeing’s Starliner capsule, NASA has been pushing back the return date from the International Space Station. On Friday, the agency announced they no longer had a planned return date. Instead, they will keep testing the capsule, trying to understand its issues, and seeing if they can make any fixes. Plenty of supplies are on the station, so there’s no urgent need to bring the two astronauts back to Earth.

Starliner Has Five Leaks

Boeing Starliner

Many space fans have been following the successful launch of the Boeing Starliner, another commercial organisation aiming to make space more accessible. It successfully reached the International Space Station, delivering Butch Wilmore and Suni Williams into orbit but it wasn’t without a hitch. Three of its thrusters experienced problems and there were ‘five small leaks on the service module.’ The crew and ground teams are working through safety checks of power and habitability. To ensure a safe return of the astronauts NASA has extended the mission by four days to 18th June.

After many delays and two scrubbed launch attempts, Boeing’s CST-100 Starliner successfully launched earlier today! The Crewed Flight Test (CFT) took off from Space Launch Complex-41 at Cape Canaveral Space Force Station, Florida, at 10:52 a.m. EDT (07:52 PDT) atop a ULA Atlas V rocket. For this mission, the capsule is carrying two NASA astronauts: Barry “Butch” Wilmore (commander) and Sunita “Suni” Williams (pilot). They are expected to reach the International Space Station (ISS) at 12:15 p.m. EDT (09:15 a.m. PDT) on Thursday, June 6th.

The International Space Station’s Air Leaks are Increasing. No Danger to the Crew

Only the other week I had to fix my leaky tap. That was a nightmare.  I cannot begin to imagine how you deal with a leaky spacecraft! In August 2020 Russia announced that their Zvezda module had an air leak. An attempt was make to fix it but in November 2021 another leak was found. Earlier this week, Russia announced the segment is continuing to leak but the crew are in no danger.

NASA is Done Setting Fires Inside its Doomed Cargo Spacecraft

NASA's Saffire program is a series of experiments designed to understand how fire behaves in a spacecraft. In this image, a sample of fabric burns inside an uncrewed Cygnus cargo craft during a previous Spacecraft Fire Safety Experiment investigation, Saffire-IV. Image Credit: NASA

Fire on a spacecraft can be catastrophic. It can spread quickly in a confined space, and for trapped astronauts, there may be no escape. It’s fading in time now, but Apollo 1, which was to be the first crewed Apollo mission, never got off the ground because of a fire that killed the crew. There’ve been other dangerous spacecraft fires too, like the one onboard the Russian Mir space station in 1997.

In an effort to understand how fire behaves in spacecraft, NASA began its Saffire (Spacecraft Fire Safety Experiment) in 2016. Saffire was an eight-year, six-mission effort to study how fire behaves in space. The final Saffire test was completed on January 9th.

An Astronaut Controls a Robotic Dog From Orbit

DLR's four-legged robot Bert explores and monitors the unfamiliar environment. The Surface Avatar Experiment rehearsed an important scenario for future exploration missions on the Moon and Mars. Bert is being developed at the DLR Institute of Robotics and Mechatronics and can walk, trot, gallop, perform a passing gait and even climb. This enables him to cover long distances and at the same time move around in rough terrain or small caves. Credit: DLR.

Swedish astronaut Marcus Wandt took control of a series of robots in Germany while on board the International Space Station, zipping around the Earth at 28,000 kilometers per hour (17,500 mph.) Researchers want to understand how time delays can affect the remote control of robots from an orbiting platform. Future astronauts could control rovers on the Moon’s or Mars’s surface from a spacecraft in orbit. Until now, only wheeled rovers have been part of the tests, but now they have added a dog-like robot called Bert.

Ouch. Canadarm2 Took a Direct Hit From a Micrometeorite

Living in space comes with risks. For astronauts on the International Space Station (ISS), those risks occasionally make themselves intrusively apparent.

Earlier this month, European Space Agency astronaut Andreas Mogensen snapped a photo of the Canadarm2, in which damage from a micrometeorite impact is clearly visible.

Dream Chaser is Getting Tested at NASA

After a journey spanning almost two decades, Sierra Nevada Corporation’s Dream Chaser reusable spaceplane, named Tenacity, is officially undergoing environmental testing at NASA’s Neil Armstrong Test Facility located at NASA’s Glenn Research Center in anticipation of its maiden flight to the International Space Station (ISS), currently scheduled for April 2024. The environmental testing consists of analyzing the spacecraft’s ability to withstand rigorous vibrations during launch and re-entry, along with the harsh environment of outer space, including extreme temperature changes and vacuum conditions. This testing comes after Sierra Space announced the completion of Tenacity at its facilities in Louisville, Colorado last month, along with the delivery of Sierra Space’s cargo module, Shooting Star, to the Neil Armstrong Test Facility that same month, as well.

The International Space Station Celebrates 25 Years in Space

25 years of ISS

NASA recently celebrated the 25th anniversary of the International Space Station (ISS) with a space-to-Earth call between the 7-person Expedition 70 crew and outgoing NASA Associate Administrator, Bob Cabana, and ISS Program Manager, Joel Montalbano. On December 6, 1998, the U.S.-built Unity module and the Russian-built Zarya module were mated in the Space Shuttle Endeavour cargo bay, as Endeavour was responsible for launching Unity into orbit that same day, with Zarya having waited in orbit after being launched on November 20 from Kazakhstan.

Red Sprites are Best Seen from Space

Planet Earth is full of some truly awe-inspiring spectacles, but few are as intriguing as a sprite, which are officially known as a Transient Luminous Event (TLE) and consist of large-scale electric discharges that shoot upwards while occurring above the cloud tops in the Earth’s mesosphere at approximate altitudes of 50-90 km (31-56 mi). In October 2023, European Space Agency (ESA) astronaut, Dr. Andreas Mogensen, who is currently onboard the International Space Station (ISS) as Commander of the Expedition 70 mission, took an incredible image of a red sprite with the Davis camera as part of the Thor-Davis experiment and his Huginn mission.
