NASA’s DART probe successfully collided with an asteroid.

At the time of impact, the impactor vehicle, about the size of a vending machine, was moving at about 14,000 mph.

After traveling for over a year, NASA‘s Double Asteroid Redirection Test (DART) mission, which attempted to provide answers, “Could a specially crafted satellite be used to divert an asteroid from its planet-destroying course? How about a number? “has effectively impacted the Dimorphos asteroid. However, NASA ground control has confirmed that the DART impact vehicle has intercepted the target asteroid. The results and data from the collision are still being received. Yes, Dimorphos is about the size of a football stadium, but space is very big, extremely dark, and both the asteroid and the spaceship were traveling rather quickly at the time.

“It’s been a successful completion of the first part of the world’s first planetary defense test,” NASA Administrator Bill Nelson said after the impact. “I believe it’s going to teach us how one day to protect our own planet from an incoming asteroid. We are showing that planetary defense is a global endeavor and it is very possible to save our planet.”

In an effort to investigate the employment of defensive satellites as a method of planetary defense against Near Earth Objects, NASA launched the DART mission in November 2021. Nearly 68 million miles from Earth, the DART impactor vehicle, about the size of a vending machine, tragically crossed Dimorphos’ path while traveling at about 14,000 MPH.

It remains to be seen if future generations of a planetary defense system will be packed with satellites ready to go full June Bug vs. Chrysler Windshield against real planet-killer asteroids. Dimorphos is one of two asteroids that are gravitationally entangled; its parent rock is more than five times larger than Dimorphos itself, but both are dwarfed by the space rock that struck Earth 66 million years ago and destroyed 75% of the planet’s multicellular life while gouging out the Gulf of Mexico.

NASA Will Make a Big Announcement About Unidentified Anomalies

NASA will release a major report on UFOs, or “unidentified anomalous phenomena” (UAP).

The briefing will be held at the agency’s Washington DC headquarters at 10:00 EDT (14:00 UTC) on Thursday, September 14. The video player below streams the discussion live.

NASA commissioned an independent study group of 16 scientific, aeronautical, and data experts led by astrophysicist David Spergel in 2022 to produce the findings.

NASA says the study group will “examine UAP from a scientific perspective and create a roadmap for how to use data and the tools of science to move our understanding of UAP forward.”

The team’s full report will be posted online by NASA 30 minutes before the briefing.

This report will be released in accordance with NASA’s openness, transparency, and scientific integrity. When the study was announced last year, NASA’s Science Mission Directorate assistant deputy associate administrator for research, Daniel Evans, said, “We take that obligation seriously and make it easily accessible for anyone to see or study.”

UAP sightings were once the domain of conspiracy theorists and sci-fi, but recent high-profile US military sightings have legitimized them.

US authorities are taking UAPs seriously because they may be Russian or Chinese experimental aircraft being tested for national security.

Also possible is extraterrestrial life. NASA is open to all possibilities, but this week’s announcement won’t reveal alien lifeforms visiting Earth.

Instead, the report may outline new protocols to help the agency collect UAP data in the future.

“The report informs NASA of future data collection opportunities to shed light on UAP’s nature and origin. The announcement’s brief NASA statement said the report is not a review or assessment of previous unidentifiable observations.

“There are currently a limited number of high-quality observations of UAP, which make it impossible to draw firm scientific conclusions about their nature,” the agency said.

Various Companies Partner Up to Put a Mobile Phone Network on the Moon

Network

The world of science and technology brings us yet another crazy possibility that’s going to be explored quite soon. Fourth Generation Cellular Networks are seeing implementations on various places. One of them could be the natural satellite orbiting the earth: The Moon.

A partnership between Nokia, Vodafone and Audi is looking to implement cellular networks on the moon sometime next year. Even if the proposition sounds crazy, it seems like they have a lot of plans to make this dream a reality.

Vodafone will be designing the lunar network and will make use of equipment designed by Nokia Bell Labs. This connectivity will allow two Audi Lunar Quattro rovers to communicate wirelessly with a base station at the Autonomous Landing and Navigation Module.

Using existing satellites, mission organizer Part Time Scientists will also be able to live stream scientific data and HD video content from the Moon to viewers on Earth. In other words, we will be getting some very detailed views of Earth for public viewing.

The networking equipment will be launched into space aboard a SpaceX Falcon 9 rocket. If you think it’s going to be very heavy and sloppy to handle. Nokia’s engineers have worked really hard to make it weigh less than one kilogram.

We’re seeing the vestiges of life in the moon very frequently now. All thanks to the options becoming more and more accessible with the fast advancements in technology. Of course, this rapid growth is far from reaching its peak potential.

Who knows? Maybe we will be able to look at interplanetary travels and living. The sky is the limit when it comes to the amount of creations. Nowadays bizarre ideas like mobile networks in different planets aren’t that far fetched eiher.

It’s going to be an interesting ride, for sure. However, we must be also conscious about the planet we’re currently living in. Even though there are efforts to make this planet greener, there is a lot left to do.

Spacesuit’s “Take Me Home” Button can help Lost Astronauts

Astronauts

Alright, it’s been some time since we’ve talked about developments in Space Technology. This development in particular can actually save the lives of countless astronauts who find themselves in quite nightmarish situations. I mean, being “lost in space” is a very serious issue for a lot of astronauts.

A recent patent made by Kevin Duda, a space systems engineer at the Charles Stark Draper Laboratory in Cambridge, Massachusetts shows a self-return system that allows safety for spacewalking astronauts. Even in the most threatening scenario of the crewmates not being able to rescue the astray spaceman.

The self-return spacesuit system, Duda explained, had to be capable of determining a precise location in a harsh space environment where GPS is unavailable. This basically makes for a “Return to Home” button that is very tricky to develop.

The system has to compute an optimal return trajectory that accounts for time, oxygen consumption, safety and clearance requirements. Not only that but the system has to be able to guide a disoriented and possibly unconscious astronaut to safety effectively.

Draper Director of Space Systems Séamus Tuohy said the return-home technology is an advance in spacesuits that is long overdue. He mentions how current spacesuits feature no navigation system and could be a very challenging aspect for astronauts in the current age.

The patent also shows how the system works. It monitors the movement, acceleration and position of the crewmember relative to a fixed object nearby. The navigation module can also be configured using GPS, vision-aided navigation or a star-tracker system.

Additionally, to improve the astronaut’s positioning and orientation, Draper has developed software that fuses data from vision-based and inertial navigation systems and that benefits from the advantages of both sensing approaches. The development of this and other kinds of spacesuits will be handled by NASA

Not only that, but this technology can be used to help Earth’s inhabitants as well. Clothing equipped with sensors of this caliber could help First Response members and even firefighters during dire situations. If you want to see the full patent listing, I’d suggest you read it right here.
