Explanation: What happens when a black hole devours a star? Many details remain unknown, but observations are providing new clues. In 2014, a powerful explosion was recorded by the ground-based robotic telescopes of the All Sky Automated Survey for SuperNovae (Project ASAS-SN), with followed-up observations by instruments including NASA's Earth-orbiting Swift satellite. Computer modeling of these emissions fit a star being ripped apart by a distant supermassive black hole. The results of such a collision are portrayed in the featured artistic illustration. The black hole itself is a depicted as a tiny black dot in the center. As matter falls...

A former Naval Academy soccer star who led her squad to an undefeated league season has been named to another team that goes above and beyond. NASA announced Friday that it had assigned Marine Corps Lt. Col. Nicole Mann to a new crew of astronauts who will fly a privately developed spaceship, marking a return of U.S.-manned space flight after the shuttle program ended in 2011. Since then, Americans have relied on Russian spacecraft for space travel. Mann will be a part of a three-person crew to fly Boeing’s Starliner spacecraft on a mid-2019 mission, the spacecraft’s first manned flight....

One of the key differences between the two is that SpaceX was awarded $2.6 billion, while Boeing receiving $4.2 billion. SpaceX completed a pad abort test in 2015, while Boeing hopes to be able to achieve this milestone possibly this year. Boeing's abort test had been scheduled for this summer, but it was delayed due to a leak of highly-toxic hydrazine from one of the abort engines. The leak occurred after the command was issued to shut down the engines. Several of the abort engine valves failed to fully close. As early as July 11, 2018, NASA internally believed (as...

Liftoff is at 1:35 p.m. EDT (1735 GMT) Designated Space Based Infrared System Geosynchronous Earth Orbit Flight 5 (SBIRS Geo-5), the mission marks ULA's first launch so far this year. However, the company has a busy summer planned, including the launch of Boeing's Starliner crew capsule to the International Space Station. That mission, called OFT-2, will be the spacecraft's second uncrewed orbital flight test. The first, which occurred in Dec. 2019, failed to reach the space station due to a software issue. Following a successful second flight test, Boeing will launch its first crew of astronauts later this year. Weather...

Boeing's Starliner spacecraft took a road trip Tuesday before its May 6 liftoff, moving from the Kennedy Space Center to the Cape Canaveral Space Force Station. Starliner boarded a transporter at the Commercial Crew and Cargo Processing Facility at Kennedy Space Center on Monday. Final checks were completed Tuesday for the short trip to the United Launch Alliance's Vertical Integration Facility at the Space Force station. "The Atlas V will receive its precious cargo today as the Boeing Space Starliner spacecraft is transported to ULA's Vertical Integration Facility and lifted onto the rocket," ULA said on X. Astronauts Butch Wilmore...

The spacecraft made its first connection with the International Space Station's (ISS) Harmony module at 8:28 p.m. EDT. Boeing said that – in addition to ground controllers in Houston – astronauts on the space station monitored Starliner throughout the flight and sometimes commanded the spacecraft to verify control capabilities. The Starliner launched on a United Launch Alliance Atlas V rocket from Florida's Cape Canaveral Space Force Station at 6:54 p.m. ET on Thursday. While docked, the crew of the station will float inside the Starliner, conduct an initial cabin tour and periodically perform system checkouts while ground controllers evaluate data...

In preparation for this second attempt at OFT-2, the Starliner capsule is currently sitting atop a United Launch Alliance Atlas V rocket, which is scheduled to launch from Space Launch Complex-41 at Cape Canaveral Space Force Station at 6:54 p.m. EDT on Thursday, May 19. Should all go as planned, the uncrewed CST-100 will dock at the International Space Station on Friday, May 20 at 7:10 p.m. EDT. Starliner OFT-2 is packed with around 500 pounds of cargo (mostly food), and the plan is to return 600 pounds of cargo back to Earth. Recent precedent being what it is, this...

Over the weekend, engineers were able to open seven of those valves and restore them to working order, the company said, and it is still hopeful that it could launch the test flight by the end of the month. But Boeing still does not know what caused the problem, which forced yet another delay in a program that has been plagued by serious issues for years. Boeing is developing Starliner under a contract with NASA to fly the space agency’s astronauts to and from the International Space Station. Elon Musk’s SpaceX, the other company that holds the “commercial crew” contract,...

The Boeing Starliner didn't see any testing shortcuts before its flawed flight test, officials said Friday, but the company vowed to expand tests in the future. Boeing (BA) stock fell. In December, the Boeing Starliner set off on an uncrewed test, but it failed to reach the International Space Station as planned because a software error prevented it from getting into the proper orbit. It was later revealed that an internal timer on the capsule was off by 11 hours, causing the Boeing Starliner to believe that it was further into the mission. Another software issue was found with the...

Boeing's spacecraft landed safely at New Mexico's White Sands Missile Range at 7:58AM Eastern, making it the first US-made, crew-ready capsule to touch down on solid ground. Previous capsules from the Mercury, Gemini and Apollo programs all landed in the sea. Boeing and NASA said during the briefing that they still expected a crewed flight in 2020, but that they wanted to review data before deciding the next course of action. There are still more dry runs to go, including an in-flight abort test to complement the launch abort test from November. While NASA is eager to reduce its dependence...

Now the capsule will be mated on top of the rocket that will take it to space — an Atlas V manufactured by the United Launch Alliance. On December 17th, the rocket and capsule are slated to take off from Cape Canaveral, Florida — without any crew members on board — and then dock with the International Space Station. If successful, this demonstration mission could pave the way for NASA astronauts to fly on the Starliner sometime next year. Boeing has been developing the Starliner spacecraft for NASA as part of the space agency’s Commercial Crew program, an initiative to...

Boeing confirmed July 21 that there was an "anomaly" during a recent test of the launch abort engines for its CST-100 Starliner commercial crew vehicle that could delay a key milestone needed for the vehicle to be able carry astronauts. The incident happened during a hot-fire test of the engines used by Starliner's abort system, integrated into a spacecraft service module. The static test, which took place in June at NASA's White Sands Test Facility in New Mexico, was a prelude to a pad abort test of the system planned for later this summer. "The engines successfully ignited and ran...

The first crewed flight of Boeing's Starliner spaceship was dramatically called off just two hours before launch after a new safety issue was identified, officials said Monday, pushing back a high-stakes test mission to the International Space Station. Astronauts Butch Wilmore and Suni Williams were strapped into their seats preparing for liftoff when the call for a "scrub" came, because engineers noticed audible buzzing from a liquid oxygen relief valve on the Atlas V rocket meant to propel the capsule into orbit. In a late night press conference, Tory Bruno, president and CEO of United Launch Alliance (ULA) that built...

Explanation: This is how the Sun disappeared from the daytime sky last month. The featured time-lapse video was created from stills taken from Mountain View, Arkansas, USA on 2024 April 8. First, a small sliver of a normally spotted Sun went strangely dark. Within a few minutes, much of the background Sun was hidden behind the advancing foreground Moon. Within an hour, the only rays from the Sun passing the Moon appeared like a diamond ring. During totality, most of the surrounding sky went dark, making the bright pink prominences around the Sun's edge stand out, and making the amazing...

Mathematicians think abstract tools from a field called symplectic geometry might help with planning missions to far-off moons and planets. In October, a Falcon Heavy rocket is scheduled to launch from Cape Canaveral in Florida, carrying NASA’s Europa Clipper mission. The $5 billion mission is designed to find out if Europa, Jupiter’s fourth-largest moon, can support life. But because Europa is constantly bombarded by intense radiation created by Jupiter’s magnetic field, the Clipper spacecraft can’t orbit the moon itself. Instead, it will slide into an eccentric orbit around Jupiter and gather data by repeatedly swinging by Europa—53 times in total—before...

Explanation: What happens to a star that goes near a black hole? If the star directly impacts a massive black hole, then the star falls in completely -- and everything vanishes. More likely, though, the star goes close enough to have the black hole's gravity pull away its outer layers, or disrupt, the star. Then, most of the star's gas does not fall into the black hole. These stellar tidal disruption events can be as bright as a supernova, and an increasing amount of them are being discovered by automated sky surveys. In the featured artist's illustration, a star has...

Explanation: Despite their resemblance to R2D2, these three are not the droids you're looking for. Instead, the enclosures house 1.8 meter Auxiliary Telescopes (ATs) at Paranal Observatory in the Atacama Desert region of Chile. The ATs are designed to be used for interferometry, a technique for achieving extremely high resolution observations, in concert with the observatory's 8 meter Very Large Telescope units. A total of four ATs are operational, each fitted with a transporter that moves the telescope along a track allowing different arrays with the large unit telescopes. To work as an interferometer, the light from each telescope is...

Explanation: A mere 280 light-years from Earth, tidally locked, Jupiter-sized exoplanet WASP-43b orbits its parent star once every 0.8 Earth days. That puts it about 2 million kilometers (less than 1/25th the orbital distance of Mercury) from a small, cool sun. Still, on a dayside always facing its parent star, temperatures approach a torrid 2,500 degrees F as measured at infrared wavelengths by the MIRI instrument on board the James Webb Space Telescope. In this illustration of the hot exoplanet's orbit, Webb measurements also show nightside temperatures remain above 1,000 degrees F. That suggests that strong equatorial winds circulate the...
