Boeing’s next uncrewed Starliner test flight set for April 2 CAPE CANAVERAL, FL –  Following a military mission delay for the U.S. Space Force, winter storms blanketed Texas, and a need for spacecraft and hardware processing time, NASA and Boeing are now targeting NET April 2, for the launch of Starliner’s second uncrewed flight test …


New video from NASA’s Mars 2020 Perseverance rover chronicles major milestones during the final minutes of its entry, descent, and landing (EDL) on the Red Planet on Feb. 18 as the spacecraft plummeted, parachuted, and rocketed toward the surface of Mars. A microphone on the rover also has provided the first audio recording of sounds …


Mars has garnered a bunch of headlines recently with the arrival of the first probes from the United Arab Emirates and China in orbit around the planet, along with the arrival of NASA’s Perseverance rover mere days later. It also was a hot topic previously when NASA revealed it had discovered water on the Red …


After enduring the harrowing ‘Seven Minutes of Terror’ plunge through the Martian atmosphere following a seven-month interplanetary journey NASA’s Perseverance rover nailed her nail-biting landing on Mars Thursday afternoon, Feb. 18, and transmitted the first two images just moments later from the floor of the Jezero Crater landing site to reveal an alien but scientifically …


Emirates Mars Infrared Spectrometer (EMIRS) aboard spacecraft developed to create first holistic picture of Martian atmosphere A veteran of multiple NASA missions to Mars, Northern Arizona University planetary scientist Christopher Edwards will closely watch the launch of a space probe to Mars that carries a unique new instrument he co-designed in collaboration with engineers from the United …


When you’re planning to explore someplace new, it’s always a good idea to bring a map so you can avoid dangerous terrain. This is true whether you’re heading out for a hike on Earth or you’re landing a rover on Mars. When NASA’s Perseverance rover lands on Mars this week, it will be equipped with some of …


In one week, NASA’s Mars 2020 mission will be arriving at the red planet, and hopefully will place the Perseverance Rover on the surface. Jim Bell is the primary investigator leading a team in charge of one of the camera systems on Perseverance. Bell is a professor in the School of Earth and Space Exploration …


Arab world’s first mission to Mars achieves orbit The Arab world’s history-making first interplanetary mission to Mars – the United Arab Emirates Hope Probe – successfully achieved orbit today, Tuesday, Feb. 9, at 10:57 a.m. ET (19:57 UAE time, 1557 GMT),” after a seven-month journey bound for the Red Planet and designed to study the …


Forget Ridley Scott’s Alien. There may be a real-life horror story in space. As one national newspaper headline has warned, the International Space Station is ‘filled with germs’. But should such a revelation really make us scream? The story stems from a new NASA study (reported in Microbiome) which found that some bacterial pathogens, including …


The “Seven Minutes of Terror” is approaching fast for NASA’s Mars 2020 Perseverance rover mission with a touchdown on the surface of the Red Planet at Jezero crater slated of occur in just under weeks on February 18. The groundbreaking astrobiology mission will continue the search for evidence of past or present life on Mars. …


Briony Horgan grew up in Portland, Oregon, where, enjoying the mountains and volcanoes that surrounded the region, she developed a love of geology. A long-standing interest in space made Horgan realize she wasn’t confined to study rocks simply on Earth. Horgan, now an associate professor of planetary science at Purdue, soon will have an opportunity …


We’ve learned a lot about the effects on the human body of going into space by studying astronauts such as British astronaut Tim Peake, who spent six months aboard the International Space Station during 2015 and 2016. Muscles wither, bones become lighter just as they do during the process of ageing and the cardiovascular system …


A recycled SpaceX Falcon 9 soared to orbit Sunday morning with a record-setting number of small satellites in a single flight on their first dedicated SmallSat Rideshare Program mission dubbed Transporter-1, also flying on a rare southern trajectory from Florida’s Spaceport.

Gravity can be a real downer when you are trying to grow organs. That’s why experiments in space are so valuable. They have revealed a new perspective into biological sciences, including insights into making human tissues. Gravity influences cellular behavior by impacting how protein and genes interact inside the cells, creating tissue that is polarized, …

Last year, it was reported that an astronaut in space had developed a potentially life-threatening blood clot in the neck. This was successfully treated with medication by doctors on Earth, avoiding surgery. But given that space agencies and private spaceflight companies have committed to landing humans on Mars in the coming decades, we may not …


DECEMBER 27, 1984: A team of American meteorite hunters finds the meteorite ALH 84001 in the Allan Hills region of Antarctica. This meteorite was found to have come from Mars, and in 1996 a team led by NASA scientist David McKay reported the presence of possible “microfossils” and other evidence of potential biological activity within …


Perihelion: 1973 December 28.43, q = 0.142 AU  This comet’s story starts about two years before its actual discovery when Brian Marsden (at the IAU’s Central Bureau for Astronomical Telegrams) performed some orbital calculations of the long-lost periodic Comet 3D/Biela (a previous “Comet of the Week”). The comet had not been seen since the mid-19th Century …


  When I first began reading about the solar system as an elementary school student in the mid-1960s, it seemed to be a much simpler place than what we know today. There was the sun, around which orbited nine planets; some of these planets had moons, Jupiter having the most with 12. Between Mars and …
