NASA Selects Two Missions to Explore the Early Solar System

I like this. It's fundamental to feed kids with vocabulary and specificites of space travel.
Whatever the gangsta elitists groups say you, there is no good engineer that began his professional career as a tiny 7 year old dreamer.
(see what computer engineering has become).

NASA’s OSIRIS-REx Mission Plans for May Asteroid Departure - OSIRIS-REx Mission

On May 10, NASA’s Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) spacecraft will say farewell to asteroid Bennu and begin its journey back to Earth. During its Oct. 20, 2020, sample collection event, the spacecraft collected a substantial...

NASA Invites Public, Media to Watch Asteroid Mission Begin Return to Earth​


NASA invites the public and the media to watch its first asteroid sample return mission begin a two-year cruise home at 4 p.m. EDT Monday, May 10, on NASA Television, the NASA app, and the agency’s website. The public can follow along on the NASA Solar System Instagram, Twitter, and Facebook accounts using #ToBennuAndBack, and ask questions about the mission by commenting on an Instagram story between 12 p.m. EDT, May 10 and 12 p.m. EDT, May 11. Answers will post to NASA Solar System’s Instagram stories on May 11.



Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) is the first NASA mission to visit a near-Earth asteroid, survey the surface, and collect a sample to deliver to Earth. During the broadcast, scientists will reveal new imagery from the mission's final flyover of the asteroid Bennu and discuss the tense moments from the sample grabin October 2020. The broadcast also will cover how the team engineered its way out of challenges that threatened its mission.



At approximately 4:16 p.m. EDT, the OSIRIS-REx control room located at Lockheed Martin, in Littleton, Colorado, will receive a confirmation that the spacecraft fired its main thrusters to push away from asteroid Bennu’s orbit, approximately 16 minutes after it happened. After 7 minutes of firing its thrusters, OSIRIS-REx will officially start its long journey home with more than 2.1 ounces (60 grams) of asteroid material.



The OSIRIS-REx departure sequence is the mission's most significant maneuver since it arrived at Bennu in 2018. The spacecraft’s thrusters must change its velocity by 595 miles per hour (958 kilometers per hour) for OSIRIS-REx's path to intersect Earth and achieve a successful sample return at the Utah Test and Training Range on Sept. 24, 2023.



There is no straight path back to Earth. Like a quarterback throwing a long pass to where a receiver will be in the future, OSIRIS-REx is traveling to where the Earth will be. The spacecraft will circle the Sun twice, covering 1.4 billion miles (2.3 billion kilometers) over to catch up with Earth.



OSIRIS-REx made history many times during its two and half years of operations on the asteroid, including breaking its own record for the closest orbit of a planetary body by a spacecraft. Bennu is the smallest celestial object ever orbited by a human-built spacecraft.



OSIRIS-REx will bring back the largest sample collected by a NASA mission since the Apollo astronauts returned with Moon rocks. Scientists plan to analyze the sample to learn about the formation of our solar system and the development of Earth as a habitable planet.



Once recovered, the capsule will be transported to the curation facility at NASA’s Johnson Space Center in Houston, where the sample will be removed for distribution to laboratories worldwide. NASA will set aside 75% of the samples for future generations to study with technologies not yet created.



NASA's Goddard Space Flight Center in Greenbelt, Maryland, provides overall mission management, systems engineering, and the safety and mission assurance for OSIRIS-REx. Dante Lauretta of the University of Arizona, Tucson, is the principal investigator. The University of Arizona leads the science team and the mission's science observation planning and data processing. Lockheed Martin Space in Littleton, Colorado, built the spacecraft and provides flight operations. Goddard and KinetX Aerospace are responsible for navigating the OSIRIS-REx spacecraft. OSIRIS-REx is the third mission in NASA's New Frontiers Program, managed by NASA's Marshall Space Flight Center in Huntsville, Alabama, for the agency's Science Mission Directorate Washington.

Maxar CEO Dan Jablonsky, Q1 2021 earnings call:

Maxar has built over 35 satellites with solar electric propulsion, using an active hall-effect thruster, including a commercial geo-conformation that exclusively uses the technology. This approach reduces fuel mass by 80% relative to traditional chemical fuel propulsion systems, allowing more allocation for revenue-generating payload mass. And this is a good thing, especially for our commercial customers who are constantly looking for ways to increase the capital efficiency of their operations.

On Slide 9, we showcase the Psyche mission as an example of how this technology can be used in deep space. As a reminder, Psyche is a NASA emission to explore a metallic asteroid. The mission will require the spacecraft to be on orbit for years and to travel 1 billion miles.

To get this done, we're using a more powerful hall-effect thruster than those used in the typical mission orbiting Earth. In fact, this will be the first time that a hall thruster has been used beyond lunar orbit, and as such, is a groundbreaking mission that could lead to a different approach in how spacecraft are powered and deep space going forward.

NASA Invites Media to New OSIRIS-REx, Asteroid Bennu Study Briefing

NASA will host a media teleconference at 1 p.m. EDT Wednesday, Aug. 11, to discuss an important finding from NASA’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft.

OSIRIS-REx spent over two years near the asteroid Bennu, which is a third of a mile (500 meters) wide. During that time, the spacecraft gathered information about Bennu’s size, shape, mass, and composition while monitoring its spin and orbital trajectory. Before leaving the near-Earth object May 10, 2021, the spacecraft scooped up a sample of rock and dust from the asteroid’s surface. OSIRIS-REx will return the sample to Earth Sept. 24, 2023, for further scientific study.

Audio of the teleconference will stream live online at:

Oh look!

Lucy's in the Sky with Diamonds!

On the morning of November 24, 1974, a hominid with 3.2 million years was discovered near the Awash River in Ethiopia. That first evening they celebrated at the camp; at some stage during the evening they named fossil AL 288-1 "Lucy", after the Beatles' song "Lucy in the Sky with Diamonds", which was being played loudly and repeatedly on a tape recorder in the camp.

Using data collected by Osiris Rex they’ve been able to rule out Bennu hitting Earth in 2135, and that has only a 0.6% chance of hitting Earth in 2182

Sorry to quote myself but did anyone see the ridiculous reporting of this as if it was certain to hit us tomorrow. In fact it’s still 99.4% not to hit us, and anyway this event isn’t until 2185.

If Bennu only has a 99.4% chance of hitting us in 2185 then there is nothing to worry about it now, it may be something to worry about for our future ancestors in 2185.

No it’s 0.6% chance of hitting us and a 99.4% chance of not hitting us. Sorry for any confusion.
 
An asteroid that large will be bad: Impact equivalent to 1-30 GT of TNT, depending on impact speed.
It will destroy an area several hundred km in diameter, and can cause global winter due to atmospheric dust. Getting close to exctinction level.

That’s why I like the idea of having both Moon and Mars bases so that if Earth does get hit in the future by an asteroid, then humanity can have somewhere to live and ride out the storm then return to Earth when it has recovered.

I have always had that idea since I was younger Flyaway, way before Elon Musk.

No I meant in term’s that it’s his motivation for Starship.
