Civil Space

Posted by in categories: engineering, space

Johns Hopkins APL’s Civil Space Mission Area makes critical contributions to NASA and international missions to meet the challenges of space science, engineering, and exploration.

Since the dawn of the Space Age, APL has pushed the frontiers of space science, engineering and exploration. We captured the first picture of Earth from space, invented navigation by satellite, dispatched spacecraft across the solar system from our Sun to Pluto and beyond, and successfully conducted the world’s first full-scale planetary defense test mission.

We continue to shape the future by providing our nation with innovative and low-cost solutions to its space challenges. Our work includes conducting research and space exploration; development and application of space science, engineering, and technology; and production of one-of-a-kind spacecraft, instruments, and subsystems.

Newly Found ‘Forbidden Planet’ Leaves Astronomers Puzzled

Posted by in category: space

A planet the same size as Jupiter has been found around a surprisingly small red dwarf star about 285 light-years from our solar system. The gas giant is so large, relative to its host star, that it threatens to up-end long-held theories about how giant planets form.

Digital restoration of historical documents

Posted by in categories: computing, space

One of the best ways to learn about any historical period is by conversing with the people who lived through it. Speaking with people from the distant past is very one-sided, as they are typically dead and have stopped listening long ago. However, they speak volumes if you have the patience to listen, or rather, read what they say in letters, diaries and primitive post-it notes with no sticky back sides.

An international group of computer scientists from Italy, the U.K. and Pakistan have teamed up to resurrect the dead from writings that have been degraded by time by developing a computer-assisted method to virtually return documents to a more legible and decipherable condition. In their research paper, “Restoration and content analysis of ancient manuscripts via color space based segmentation,” published in the journal PLOS ONE, the team details their digital restoration technique’s method and experimental results.

We get a sense of ancient civilizations from their writings, both trivial and profound. The Sumerian cuneiform writing on reveals 4,000-year-old merchant transactions, geometric calculations, and poetry detailing the fall of a great city. Had they been written on paper and not in clay we would likely not have them today.

Asteroid discovery suggests ingredients for life on Earth came from space

Posted by in categories: biological, chemistry, space

March 21 (Reuters) — Two organic compounds essential for living organisms have been found in samples retrieved from the asteroid Ryugu, buttressing the notion that some ingredients crucial for the advent of life arrived on Earth aboard rocks from space billions of years ago.

Scientists said on Tuesday they detected uracil and niacin in rocks obtained by the Japanese Space Agency’s Hayabusa2 spacecraft from two sites on Ryugu in 2019. Uracil is one of the chemical building blocks for RNA, a molecule carrying directions for building and operating living organisms. Niacin, also called Vitamin B3 or nicotinic acid, is vital for their metabolism.

The Ryugu samples, which looked like dark-gray rubble, were transported 155 million miles (250 million km) back to Earth and returned to our planet’s surface in a sealed capsule that landed in 2020 in Australia’s remote outback for analysis in Japan.

Radical NASA Propulsion Concept Could Reach Interstellar Space in Under 5 Years

Posted by in category: space

A newly proposed propulsion system could theoretically beam a heavy spacecraft to outside the confines of our Solar System in less than 5 years – a feat that took the historic Voyager 1 probe 35 years to achieve.

The concept, known as ’pellet-beam’ propulsion, was awarded an early-stage US$175,000 NASA grant for further development earlier this year.

To be clear, the concept currently doesn’t exist much beyond calculations on paper, so we can’t get too excited just yet.

Hubble telescope unravels the weather secrets of Jupiter and Uranus

Posted by in category: space

The Hubble Space Telescope’s remarkable observations shed light on the seasonal shifts and atmospheric conditions of Jupiter and Uranus.

The Hubble Space Telescope has been fundamental in unraveling the mysteries of our solar system. The telescope is a celestial weather observer that studies the changing atmosphere of giant gaseous planets. By observing climatic variations, scientists are unlocking new understanding about the dynamic weather systems of these gas giants, paving the way for a deeper understanding of our solar system.

Recently, it disclosed exquisite details about the changing weather patterns and seasonal shifts on Jupiter and Uranus.

Relativity’s first 3D-printed rocket launches successfully but fails to reach orbit

Posted by in categories: 3D printing, space

Relativity Space, a 3D-printing specialist, launched the inaugural flight of its Terran 1 rocket late on Wednesday night, which successfully met some mission objectives before failing to reach orbit.

Terran 1 lifted off from LC-16, a launchpad at the U.S. Space Force’s facility in Cape Canaveral, Florida, and flew for about three minutes. While the rocket cleared a key objective — passing the point of maximum atmospheric pressure during an orbital launch, known as Max Q — its engine sputtered and shut down early, shortly after the second stage separated from the first stage, which is the larger, lower portion of the rocket known as the booster.

Relativity launch director Clay Walker confirmed that there was an “anomaly” with the upper stage. The company said it will give “updates over the coming days” after analyzing flight data.
