“Engineers with NASA’s Europa Clipper mission continue to conduct extensive testing of transistors that help control the flow of electricity on the spacecraft. NASA’s Jet Propulsion Laboratory in Southern California, which manages the mission, began the tests after learning that some of these parts may not withstand the radiation of the Jupiter system, which is the most intense radiation environment in the solar system.”
–NASA statement from yesterday regarding potential issues with electrical switches on the Europa Clipper spacecraft that is set to launch in October. Whether this leads to a delayed launch of the mission or a less nimble mission has yet to be determined. The preliminary findings from the current testing are expected to be released later this month.
A NASA space telescope designed to “hunt” asteroids and comets that could pose a threat to life on Earth and orbiting spacecraft will soon burn up in orbit. In late 2024 or early 2025, the agency’s Near-Earth Object (NEO) Wide-field Infrared Survey Explorer—or NEOWISE—is expected to come home in pieces following the conclusion of its second mission later this month…However, NASA has a replacement lined up: the Near Earth Object Surveyor (NEO Surveyor), set for a 2027 launch. The infrared space telescope is the first to be designed specifically for hunting large numbers of NEOs in and around Earth orbit. It has a baseline development cost of $1.2 billion to which NASA committed in 2022.
Four volunteers who spent more than a year living in a 1,700-square-foot space created by NASA to simulate the environment on Mars have emerged. The members of the Crew Health and Performance Exploration Analog mission — or CHAPEA — walked through the door of their habitat at NASA’s Johnson Space Center in Houston on Saturday to a round of applause…Haston and the other three crew members — Anca Selariu, Ross Brockwell and Nathan Jones — entered the 3D-printed Mars replica on June 25, 2023, as part of a NASA experiment to observe how humans would fare living on the Red Planet.
Russia is aiming to create the four-module core of its planned new orbital space station by 2030, its Roscosmos space agency said on Tuesday. The head of Roscosmos, Yuri Borisov, signed off on the timetable with the directors of 19 enterprises involved in creating the new station. The agency confirmed plans to launch an initial scientific and energy module in 2027. It said three more modules would be added by 2030 and a further two between 2031 and 2033.
Remember asteroid 2024 MK from last Saturday? Well, NASA has some nice shots (shown above) of the asteroid as it made it close approach to the Earth. It shows the 500 foot-wide asteroid in all of its scary glory. We were lucky to be nothing but observers that day.
Another asteroid that shot by the Earth on June 27th at a distance that was about 17 time the distance between the Earth and the Moon was asteroid UL21. This asteroid was not a surprise, having been spotted back in 2011. However, it had a surprise when viewed up close. The asteroid had its own moon (shown below).
I’m impressed we have these amazing images, but if they price for these images is a risky rendezvous then I can live without them.
Note: Another asteroid is coming our way next week – asteroid 2024 MT1. The asteroid is 260 feet in diameter and will be come much closer than UL21, or about four times the distance between the Earth and the Moon.

“Selecting a U.S. Deorbit Vehicle for the International Space Station will help NASA and its international partners ensure a safe and responsible transition in low Earth orbit at the end of station operations. This decision also supports NASA’s plans for future commercial destinations and allows for the continued use of space near Earth…The orbital laboratory remains a blueprint for science, exploration, and partnerships in space for the benefit of all.”
–Statement by Ken Bowersox, associate administrator for Space Operations Mission Directorate at NASA Headquarters in Washington, regarding NASA announcement that SpaceX has been selected to develop and deliver the U.S. Deorbit Vehicle under a contract worth $843 million. This expensive Deorbit Vehicle should help to avoid problems on the ground as well as orbiting debris impacting space missions, as was the case on the International Space Station (ISS) a few days ago. The ISS is expected to continue operation until 2030.
While Matt Damon relied on potatoes cultivated in crew biowaste to survive in the hit film The Martian, researchers say it is a humble desert moss that might prove pivotal to establishing life on Mars. Scientists in China say they have found Syntrichia caninervis – a moss found in regions including Antarctica and the Mojave desert – is able to withstand Mars-like conditions, including drought, high levels of radiation and extreme cold.
Hundreds of basketball-size space rocks slam into Mars each year, leaving behind impact craters and causing rumblings across the red planet, according to new research. Mission planners could use the revelations, recorded in data collected by a now-retired NASA mission, as they determine where to land future robotic missions as well as astronaut crews on the red planet. NASA’s InSight mission ended when the stationary lander lost a battle to an accumulation of Martian dust on its solar panels in December 2022, but the wealth of data the spacecraft collected is still fueling new research.
The first volunteer crew, to live for more than a year inside NASA’s Mars habitat at the Johnson Space Center in Houston, will exit the simulated Red Planet ground mission on Saturday…The crew entered CHAPEA on June 25, 2023, and enacted Mars mission operations, including virtual reality “Mars-walks” while growing and harvesting vegetables to supplement their shelf food. They also spent their time maintaining equipment while being tested with stressors, including isolation and communication delays with Earth.
