Astronomer manages to photograph a US experimental ship Boeing X-37B in the orbit of the Earth

Astronomer and professional photographer Ralf Vandebergh took photographs of the unmanned device while moving 300 kilometers up. Little is known of this classified project, initiated by NASA and currently addressed by Boeing and the United States Department of Defense (DARPA).

A Dutch astronomer specializing in satellite monitoring captured the first images of the mysterious spacecraft Boeing X-37B, which is believed to hold the future of the US space program, orbiting the Earth.

Ralf Vandebergh, who is dedicated to taking pictures of planets and satellites from his base in Nijswiller, many of which have been used officially by NASA, published his find last week on his Twitter account.

There you can see the raw and processed image of the Boeing X-37B, an unmanned vehicle that would be testing systems for a new space shuttle, orbiting the earth at about 300 kilometers altitude on a mission called OTV-5 (Orbital Test Vehicle, or Orbital Test Vehicle).

The astronomer had been trying to take a picture of the X-37B, of which little is really known, for months and finally managed to detect its trajectory in May.

Preparing the photo, taken with an ALCCD 5L-11 mono CMOS and 5-inch F / 4.8 telescope, required a little more time.

«When I tried to observe it again in mid-June, it did not fulfill the trajectory and the expected time. Apparently, he had maneuvered into another orbit. Thanks to the amateur network of satellite observers, it was quickly found again and I was able to take the images on June 30 and July 2, “Vandebergh explained.

Although the images of the small spaceship are blurred, they have exceeded Vandebergh’s expectations: “We can recognize a bit of the nose, cargo area and tail of this mini-ferry, even with some details”.

Unknown objective

The OTV-5 mission ( the fifth of its kind ) of this X-37B began on September 7, 2017, after being launched by a Falcon 9 rocket from SpaceX from the Kennedy Space Center (KSC) in Florida, United States.

Its role and objectives are classified and little is known about its real capabilities, although it is believed that it would be collecting data, information, and intelligence, in addition to testing numerous equipment and components.

It is also not known when this mission that will take almost 700 days will end. The last X-37B (OTV-4) landed at the KSC on May 8, 2017, after 718 days orbiting, and it is expected that the OTV-6 will be launched sometime in 2019.

The Interstellar Research Initiative plans to send people to the exoplanet of Proxima Centauri b

In an attempt to protect humanity from extinction in the event of some kind of global catastrophe of a planetary scale, a group of scientists announced a bold plan for the colonization of a distant exoplanet.

Proxima Centauri b

Scientists from the Initiative for Interstellar Studies said they were considering sending people to a potentially inhabited exoplanet in another stellar system.

The most promising option they consider, Proxima Centauri b, which is 4.24 light years away from Earth, which means the journey will take centuries or even millennia. This suggests that generations will succeed each other during the journey.

Technically, this is possible.

However, the challenges facing the mission are so numerous and complex that it can take decades to prepare.

“From the point of view of physics, there are no fundamental obstacles. There are many nuances, but this is not a violation of the fundamental laws of physics, ”said Andreas Hein, Executive Director of Initiative for Interstellar Studies.

No problem.

The main problem is the lack of experience being far beyond the Earth for such a period of time.

Even a flight to Mars, which will last about 6-8 months, raises a lot of questions.

Proxima Centauri b

There is no reliable protection against merciless radiation yet. Medical problems caused by a prolonged stay in space are still poorly understood. Other than that, there is no guarantee that Proxima Centauri b is indeed liveable.

Can you imagine what a setup would be if people born on a spaceship for one purpose would come to a planet absolutely unsuitable for settlement …

However, the authors of the project do not plan to curtail the program and continue to work actively in this direction.

European Space Agency to launch space waste collector

A four-armed robotic junk collector will be launched into space by the European Space Agency in what it says will be the first mission to remove an item of debris from orbit.

European Space Agency to launch space waste collector

The ClearSpace-1 mission, scheduled for launch in 2025, will cost €120m and will grab a single piece of junk. But the agency hopes the mission will pave the way for a wide-reaching clear-up operation, with Esa’s director general calling for new rules that would compel those who launch satellites to take responsibility for removing them from orbit once they are retired from use.

Jan Wörner, CEO of ESA, said:

Imagine how dangerous sailing the high seas would be if all the ships ever lost in history were still drifting on top of the water. That is the current situation in orbit, and it cannot be allowed to continue.

In the past 60 years, thousands of tonnes of junk has accumulated around the Earth, including old rocket parts, about 3,500 defunct satellites and an estimated 750,000 smaller fragments, some from collisions between larger bits of junk. The fragments are typically circulating with a velocity of 20,000km/h (12,500mph).

Unless a clear-up operation is mounted, the chances of collisions will escalate as thousands more satellites are put into orbit.

Funding for the mission was agreed at Space19+, ESA’s misterial council, which took place in Seville, Spain, at the end of November. The mission will be run by a consortium led by a Swiss startup called Clearspace.

The target for ClearSpace-1 is a piece of junk called Vespa, which was left in an orbit around 800km above the Earth by ESA’s Vega launcher in 2013. Vespa weighs 100kg – around the size of a small satellite – and was selected because it has a simple shape and sturdy construction, which make it unlikely to fragment when it is grabbed.

The “chaser” ClearSpace space probe will be launched into the target orbit where it will track down Vespa, grab it using a quartet of robotic arms and drag it out of orbit, with Vespa and the chaser both burning up in the atmosphere on the way down to Earth.

A future ambition is to create a clear-up robot that could eject junk into the atmosphere, before continuing to capture and de-orbit other pieces of junk.

Asteroid as big as the pyramids on its way and could zoom past Earth on Friday

An asteroid as big as the Egyptian pyramids is zooming towards Earth and will squeeze past us on Friday – if it doesn’t smash on to our home planet’s surface.

Named 2019 WR3, NASA expects the space rock to make a “close approach” to Earth later this week.

The space agency has classified the asteroid as a “near-Earth object (NEO)” which means its orbit brings it very close – in cosmic terms – to Earth.

The asteroid was first spotted late last week.

NASA has now observed the asteroid some 74 times to better get a sense of its size and trajectory.

WR3 is believed to have a diameter of between 76m to 170m.

It is expected that on December 6, the asteroid will pass within 5.44 million km of Earth at speeds of 27,036 km/hr.

The warning comes as the European Space Agency approves a $471 million mission called Hera to examine whether a rogue asteroid on its way to Earth could be deflected out of the way.

Working with NASA, the ESA will send a pair of spacecraft to a double-asteroid system called Didymos to examine the asteroids and send valuable data back home.

The larger asteroid Didymoon is about 800m across, orbited by a moon about 160m wide.

If an asteroid the size of Didymoon were to hammer into Earth, it would be devastating.

Patrick Michel, ESA’s lead scientist for Hera, said it was vital to keep an eye on it so we can take action if needed.

“The probability is low but the consequences are high,” Michel told Space.com.

“This is why it’s relevant to take care of it. Moreover, we have the tools … We can’t lose more time.”

The Hera spacecraft will launch in 2024.

Meanwhile, Queens University Belfast professor Alan Fitzsimmons has called for amateur astronomers to assist the Hera mission’s broader goal of protecting Earth against asteroids by nominating asteroids to watch.

“We will get a serious asteroid impact sometime,” he told the BBC.

“It may not be in our lifetime, but mother nature controls when that will happen.

‘We will get a serious asteroid impact sometime.’

“We will need to do something about it. We’ll need to move that asteroid so it misses us and doesn’t hit us.

“Asteroid research is one area of astronomy where amateur observes continue to make an essential contribution,” he said.
