Scientific real-time map tracking 200 'ticking time bombs' near Earth

Jak Connor | Apr 26, 2021 6:35 AM CDT

Researchers and scientists are tracking thousands of human-made objects that are orbiting around Earth that could potentially be very dangerous to functioning satellites.

Scientific real-time map tracking 200 'ticking time bombs' near Earth 500

Professor Moriba and his colleagues have created a near real-time map that is called AstriaGraph that tracks around 200 "super-spreaders", which are large rocket bodies that could potentially break into thousands of pieces. A video on the BBC website details that the AstriaGraphic system is tracking over 26,000 individual objects that range from the size of a smartphone to the size of the Space Station.

Of those objects, 3,500 are functional satellites, and the rest are considered space junk or rubbish. These "super-spreaders" that Prof Moriba is concerned about are used rocket parts that are "pretty much ticking time bombs" that will eventually explode or get hit by another object and become tens of thousands of pieces that will endanger functional satellites.

Collision risk: SpaceX to fly 4,000 Starlink satellites at same height

Jak Connor | Apr 26, 2021 3:32 AM CDT

SpaceX is very close to receiving approval from the Federal Communications Commission (FCC) to fly 4,000 Starlink satellites at the same altitude in Low Earth Orbit (LEO).

Collision risk: SpaceX to fly 4,000 Starlink satellites at same height 10

The space agency has already received approval from the FCC to launch 1,584 Starlink satellites at an altitude of 550 kilometers. Now, SpaceX is looking to bring in the already positioned Starlink satellites from 1,000 kilometers to 550 kilometers so they all line up together at the same altitude. In total, SpaceX will have 4,408 satellites at an altitude of between 540 to 570 kilometers.

FCC's acting chairwoman, Jessica Rosenworcel, has backed SpaceX's request to fly all of the Starlink satellites at the same altitude and has called for a vote, according to Bloomberg. Rival companies such as Amazon's Project Kuiper, ViaSat, OneWeb, and Telesat all have plans to launch their own satellites into low earth orbit. Visat said back in March that having 1,000's of satellites in low earth orbit would increase the chance of collisions, which would leave concerning debris in space.

Elon Musk says new SpaceX rocket could fly people to the Moon in 2024

Jak Connor | Apr 26, 2021 2:39 AM CDT

Elon Musk has said that SpaceX's new rocket may be able to take people to the Moon by 2024, stating that the task is "doable".

Elon Musk says new SpaceX rocket could fly people to the Moon in 2024 01

According to Musk, SpaceX is currently underway developing its new rocket that will take the crown for the space company's biggest rocket yet. The new rocket is called Starship, and eventually, it will carry people to Mars, but the first stop is the Moon. During a press briefing on Friday last week, Musk said that Starship could fly its first humans to the Moon in "a couple years".

Here's what Musk said, "I tend to be somewhat optimistic with respect to schedules. I feel I should acknowledge this. So take that with a grain of salt. But I think it's not out of the question that it could fly people in a couple years." As for bookings, SpaceX has already taken a booking from Japanese billionaire Yusaku Maezawa, who will take a trip aboard Starship with eight friends to go around the Moon in 2023, marking the very first civilian passengers to step foot on SpaceX's Starship.

Water shortage to bring mandatory water cuts to Arizona and Nevada

Jak Connor | Apr 24, 2021 5:34 AM CDT

A new report indicates that the U.S. Bureau of Reclamation may issue a Water Shortage Declaration that would usher in water cuts to primarily two states.

Water shortage to bring mandatory water cuts to Arizona and Nevada 04

According to a report from Interesting Engineering, in August, the U.S. Bureau of Reclamation may, for the first time in history, issue a Level 1 Water Shortage Declaration that would usher in mandatory cuts in water consumption.

In the last week, the Bureau released a 24-month long projection for the water contained in the Colorado River where it stated that both of the U.S.'s two largest reservoirs are sitting at 35.53% of its full capacity (Lake Powell), and 42.97% of its full capacity (Lake Mead). Additionally, models have indicated that by June 2021, the water level at Lake Mead will fall by 1,075 feet, which will trigger the Level 1 Water Shortage Declaration affecting Arizona, Nevada, and California.

First supermoon of 2021 'pink moon' this Monday, here's how to spot it

Jak Connor | Apr 24, 2021 4:34 AM CDT

The first supermoon of 2021 will happen this coming Monday, and if you want to spot the rare sighting, you will need to know the time.

First supermoon of 2021 'pink moon' this Monday, here's how to spot it 01

The first supermoon will happen on Monday night, and it's known as the "Pink Moon". The naming comes from a pink spring flower that is found throughout North America and not what color the moon will actually appear. As for timing, the Pink Moon will be highest in the sky over at 11:32 pm Eastern Time Monday night and will also be "full" on Tuesday night as well.

Why does a supermoon happen? A supermoon occurs when the moon's orbit is closest to Earth, or more specifically, when it's within 90% of its pedigree (383,024km away). NASA says that supermoons occur only a few times a year, even though the moon only takes 27 days to orbit Earth fully. The moonrise will be at 7:24 pm in New York City. If you happen to miss this supermoon and are wondering when the next one will be, the next one will be on May 26.

NASA's small Ingenuity helicopter takes a big flight off Mars surface

Jak Connor | Apr 24, 2021 3:33 AM CDT

It was only a few days ago that NASA achieved the first off-Earth flight with its small helicopter located on Mars.

The first flight from the small helicopter named Ingenuity consisted of the helicopter lifting off from the surface of the red planet, hovering for 30 seconds at just 10 feet, and then descending back down to the baron world. Now, NASA has completed the second flight for Ingenuity, and this time around, the flight consisted of 52 seconds, climbed to 16.5 feet, hovering, tilting, and moving side to side at a distance of 6.5 feet.

Officials with NASA's Jet Propulsion Laboratory in Southern California wrote on Twitter, "Go big or go home! The Mars Helicopter successfully completed its 2nd flight, capturing this image with its black-and-white navigation camera." Ingenuity project manager MiMi Aung of NASA's Jet Propulsion Laboratory in Southern California said, "Then Ingenuity will come to a stop, hover in place and make turns to point its color camera in different directions before heading back to the center of the airfield to land."

Watching NASA's new '2 black holes orbiting' animation is hypnotizing

Jak Connor | Apr 22, 2021 9:06 AM CDT

Black holes are a thing of mystery, but at the center of every galaxy, there is one, and sometimes when two galaxies merge, those two black holes begin to enter each other's orbits.

So, what happens when two black holes enter each other's orbits? NASA has released a new animated video on the NASA Goddard YouTube Channel that gives a simple yet beautiful visualization of what begins to happen. The orange black hole is 200 million times the mass of the Sun, and the blue black hole is about 100 million times the mass of the Sun.

As the black holes approach each other on their orbital path, the gravitational pull of the foreground black hole begins to "distort and redirect light emanating from the maelstrom of hot gas - called an accretion disk - that surrounds each one", NASA explains. Jeremy Schnittman, an astrophysicist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, who created the visualization, said, "We're seeing two supermassive black holes, a larger one with 200 million solar masses and a smaller companion weighing half as much".

If you walked around the moon how long do you think it would take?

Jak Connor | Apr 22, 2021 8:34 AM CDT

So far, only 12 humans have ever stepped foot on the surface of the moon, but let's say lucky number 13 wanted to be the first human to walk around the moon. How long would it take?

If you walked around the moon how long do you think it would take? 02

In a recently published space.com article, it states that astronauts that landed on the moon during the Apollo missions were bouncing around the surface at the pace of 1.4 mph. The lack of speed from these astronauts can be attributed to their spacesuits not being built for mobility.

In 2014, NASA simulated lunar gravity to measure how fast humans could move on the moon if given the right equipment. The participants of the experiment were able to walk at the speed of 3.1 mph, very close to the maximum walking speed humans can achieve on Earth at 4.5 mph.
