Explanation: Still bathed in sunlight, the International Space Station arced through the evening sky over lake Wulfsahl-Gusborn in northern Germany, just after sunset on March 25. The familiar constellation of Orion can be seen left of the trail of the orbital station's bright passage. On the right, Venus is the brilliant evening star above the western horizon. With the camera fixed to a tripod, this scene was captured in a series of five exposures. How can you tell? The short time delay between the end of one exposure and the beginning of the next leaves small gaps in the ISS...

Gravitational waves are caused by calamitous events in the Universe. Neutron stars that finally merge after circling each other for a long time can create them, and so can two black holes that collide with each other. But sometimes there's a burst of gravitational waves that doesn't have a clear cause. One such burst was detected by LIGO/VIRGO on January 14, and it came from the same region of sky that hosts the star Betelgeuse. Yeah, Betelgeuse, aka Alpha Orionis. The star that has been exhibiting some dimming behaviour recently, and is expected to go supernova at some point in...

When you take a look at the stars in the night sky, they generally appear the same regardless of time. Only a small number of stars ever appear to change on human timescales, as most stars burn through their fuel very stably, with almost no variation in their continuous brightness. The few stars that do appear to change are either intrinsically variable, members of multi-star systems, or go through an enormous evolutionary change. When very massive stars get close to the end of their lives, they start varying by tremendous amounts, and do so with significant irregularity. At a critical...

When a rocket carrying the first module of the International Space Station blasted off from Kazakhstan in November of 1998, NASA officials said that the station would serve as an orbiting home for astronauts and cosmonauts for at least 15 years. It's now been over 18 years that the station has been continuously occupied by people. The place is impressive, with more living space than a six-bedroom house, two bathrooms and a large bay window for looking down at Earth. NASA and its international partners have spent decades and more than $100 billion to make the station a reality. The...

NASA's lunar mobile launcher is one step closer to sending its first spacecraft to the moon. The launcher is now in final testing for Artemis 1 — an uncrewed test trip around the moon of the Orion spacecraft slated for 2020 or so — after making its last solo trip to the Kennedy Space Center Launch Pad 39B on June 27. The launcher will remain at the pad for two months before going inside the nearby Vehicle Assembly Building (VAB) to join the Orion capsule and its rocket, called the Space Launch System (SLS). One day, this same system could...

NASA is in final preparation stages for its Artemis 1 moon mission, which will be the first in its Artemis series of missions which intend to return an American man to the Moon, and bring an American woman to the surface of Earth’s natural satellite for the first time. The 335-ft tall mobile launch tower that will send Artemis 1’s Orion capsule to lunar orbit atop a Space Launch System rocket is now on the pad for its last round fo testing before the real thing. NASA’s Artemis 1 mission will fly the Orion crew capsule to space, where it’ll...

Lockheed Martin is unveiling new designs for a human lunar lander concept that can take people to and from the lunar surface. And the company says it can be ready within the next five years.... The vehicle consists of two elements: a lander portion that can travel down to the ground, and an ascent vehicle that can lift astronauts off the Moon’s surface. The lander is meant to travel to and from a new space station that NASA wants to build around the Moon called the Gateway. If all of these elements are created, astronauts would travel to the Gateway...

Now, government officials are dialing up the pressure on Boeing to speed up development of the long-overdue rocket, called Space Launch System or SLS. The space agency contracted Boeing in 2012 to build SLS's core components. Bridenstine's remarks came after US Vice President Mike Pence said Tuesday at a National Space Council meeting in Alabama that news of more hangups with the SLS program were a "great disappointment," and the current timeline is "just not good enough." Boeing began building SLS's core stage, the backbone of the rocket, about seven years ago. Officials said at the time that SLS would...

In November 2016, astronomers watched a young star some 1,500 light-years away from Earth belch out an explosion of plasma and radiation that was roughly 10 billion times more powerful than any flare ever seen leaving Earth's sun. This sudden stellar eruption may be the most luminous known flare ever released by a young star — and it could help scientists better understand the still-murky process of star formation. "Observing flares around the youngest stars is new territory and it is giving us key insights into the physical conditions of these systems," Steve Mairs, an astronomer and lead author of the study, said...

NASA has accepted delivery of a key European part needed to power the world’s next-generation moonship. U.S. and European leaders gathered at Kennedy Space Center on Friday to mark the occasion. The newly arrived powerhouse, or service module, will propel NASA’s Orion capsule to the moon during a test flight without passengers planned for 2020. A mega rocket under development by NASA, known as SLS for Space Launch System, will launch the combo. […] Orion and the attached service module are meant to fly near the moon, but not land. Future missions will carry astronauts, with the goal of building...

Exploration Mission-1, which is scheduled to take place in 2020, will consist of an uncrewed Orion capsule being sent into orbit around the Moon and then returning to Earth. Using lunar gravity to gain speed and propel itself 70,000 km beyond the Moon – and almost half a million km from Earth – this mission will send a spacecraft farther into the Solar System than ever before. The Orion pressure vessel, which is the vehicle’s primary structure that will hold a pressurized atmosphere for the astronauts, consists of seven large aluminum pieces that are welded together using a state-of-the-art process...

"In a surprising move, the popular cooler making company YETI has announced it will be cutting ties with the National Rifle Association" ...Freepers, time to give Yeti a serious lesson. See link below.

On April 21 Breitbart News reported on a NRA-ILA statement which said Yeti Coolers had cut ties with the NRA Foundation. The statement, written by former NRA president and USF executive director Marion Hammer, said, “Suddenly, without prior notice, YETI has declined to do business with The NRA Foundation saying they no longer wish to be an NRA vendor, and refused to say why. They will only say they will no longer sell products to The NRA Foundation.”

Update: Austin-based Yeti says claims made by the National Rifle Association over the weekend are “inaccurate” and that the company is “unwavering in our belief in and commitment to the Constitution of the United States and its Second Amendment.” In an email to its members, the NRA claimed Yeti “suddenly, without prior notice” indicated it no longer wished to do business with the NRA Foundation. Not so, says Yeti. The maker of coolers and thermal mugs says the NRA has twisted its words. “A few weeks ago, Yeti notified the NRA Foundation, as well as a number of other organizations,...

Yeti Coolers, a go-to for sportsmen around the country, is cutting ties with the NRA Foundation without explanation or prior notice. The NRA Foundation is a charitable organization. The separation comes although Yeti products have long been a staple at Friends of NRA Foundation Banquets and functions. NRA-ILA quoted NRA past president and USF executive director Marion Hammer saying, “Suddenly, without prior notice, YETI has declined to do business with The NRA Foundation saying they no longer wish to be an NRA vendor, and refused to say why. They will only say they will no longer sell products to The...

For the April 5, 2018 John Batchelor Show; science-writer Bob Zimmerman discusses his recent tour of Biosphere-2, and updates on the effects of the Bush/Obama Policy concerning the SLS/Orion boondoggle.

The bureaucrats in Washington really have little interest in safety, but instead are more focused in putting their thumbs on the scale in order to specifically harm the commercial space companies -- especially SpaceX's. One report in particular, by NASA's Aerospace Safety Advisory Panel (ASAP), was especially hostile to these private efforts, even as it remained completely unconcerned about similar but far worse safety issues that exist with NASA's government-built and competing SLS and Orion programs.

This weekend presents the Orionid meteor shower at its best, and tonight – the night of October 20-21, 2017 – may well be the shower’s peak night. Late Saturday night and Sunday morning may be good times to watch as well. On both of these nights, meteors should become visible starting at late evening. They’ll probably be most prolific in the few hours before dawn on October 21, but try watching before dawn on October 22, too. From a dark site, you might see a maximum of about 10 to 15 meteors per hour. Fortunately, today is only one day...

An angry monster lurks in the shoulder of the Hunter. We’re talking about the red giant star Betelgeuse, also known as Alpha Orionis in the constellation Orion. Recently, the Atacama Large Millimeter Array (ALMA) gave us an amazing view of Betelgeuse, one of the very few stars that is large enough to be resolved as anything more than a point of light. 650 light years distant, Betelgeuse is destined to live fast, and die young. The star is only eight million years old – young as stars go. Consider, for instance, our own Sun, which has been shining as a...
