Solar Activity Forecast for Next Decade Favorable for Exploration

(12.06.2019)

The Sun’s activity rises and falls in an 11-year cycle. The forecast for the next solar cycle says it will be the weakest of the last 200 years. The maximum of this next cycle – measured in terms of sunspot number, a standard measure of solar activity level – could be 30 to 50% lower than the most recent one. The results show that the next cycle will start in 2020 and reach its maximum in 2025.

Cassini Tastes Organic Material at Saturn’s Geyser Moon

(26.03.2008)

The Ion and Neutral Mass Spectrometer saw a much higher density of volatile gases, water vapor, carbon dioxide and carbon monoxide, as well as organic materials, some 20 times denser than expected. This dramatic increase in density was evident as the spacecraft flew over the area of the plumes.

Low-mass nitrogen-, oxygen-bearing, and aromatic compounds in Enceladean ice grains

Previous analyses inferred three different spectral types of Enceladean ice grains (Postberg et al. 2008, 2009a): Type 1 represents grains of almost pure water ice, Type 2 shows features consistent with grains containing significant amounts of organic material, and Type 3 is indicative of salt-rich water ice grains.

Organic compounds have been found on Saturn’s moon Enceladus

Before NASA’s Cassini mission studied Saturn and its moons for 13 years, beginning in 2004, Enceladus held many secrets. Cassini revealed that there was a global ocean between the moon’s icy crust and its rocky core.

Although the Cassini mission ended in a blaze of glory when it disintegrated in Saturn’s atmosphere, surprises from the data it collected will be released for years to come.

Controlled Impact Demonstration 1984 NASA FAA CID Test Video

Published on Mar 17, 2017
This short NASA film describes the Controlled Impact Demonstration test, where NASA tested anti-misting safety measures on a remote controlled Boeing-720 aircraft. The anti-misting devices were supposed to make the use of aircraft fuel safer for passengers aboard commercial aircraft, but the FAA abandoned the project after this test.

NASA’s InSight Detects First Likely ‚Quake‘ on Mars

(23.04.2019)

The faint seismic signal, detected by the lander’s Seismic Experiment for Interior Structure (SEIS) instrument, was recorded on April 6, the lander’s 128th Martian day, or sol. This is the first recorded trembling that appears to have come from inside the planet, as opposed to being caused by forces above the surface, such as wind. Scientists still are examining the data to determine the exact cause of the signal.

Chandrayaan 2 Launch Called Off Today After „Technical Snag“

The launch of Chandrayaan 2, India’s most ambitious space mission yet, was called off early this morning by the Indian Space Research Organisation or ISRO. The powerful GSLV Mark III rocket was set to go up from Sriharikota in Andhra Pradesh at 2:51 am with a rover that would land on the moon in about two months‘ time. However, after first being put on hold 56 minutes before blast-off, the launch was scrapped because of a „technical snag“, ISRO said, adding it would announce a new date later. President Ram Nath Kovind was present at the space port for the mission.

Solar Activity Forecast for Next Decade Favorable for Exploration

(12.06.2019)

Previously, researchers used the number of sunspots to represent indirectly the activity of the solar magnetic field. The new approach takes advantage of direct observations of magnetic fields emerging on the surface of the Sun – data which has only existed for the last four solar cycles.

The Thermosphere Responds to a Weaker Than Normal Solar Cycle

The cooling near solar minimum is natural and specific to the thermosphere. The cooling thermosphere does not affect the troposphere, the layer of the atmosphere closest to Earth’s surface where people live. The temperatures we experience on the ground do not get colder because of this solar cycle. NASA and other climate researchers continue to see a warming trend in the troposphere. These two effects are ongoing but unrelated.

Nitric oxide and carbon dioxide play important roles in cooling the thermosphere.

Scientists predict sun’s activity will be weak during next solar cycle

(8. April 2019)

„We expect Solar Cycle 25 will be very similar to Cycle 24: another fairly weak cycle, preceded by a long, deep minimum,“ said panel co-chair Lisa Upton, Ph.D., solar physicist with Space Systems Research Corp. „The expectation that Cycle 25 will be comparable in size to Cycle 24 means that the steady decline in solar cycle amplitude, seen from cycles 21-24, has come to an end and that there is no indication that we are currently approaching a Maunder-type minimum in solar activity.“

First Likely Marsquake Heard by NASA’s InSight

This video and audio illustrates a seismic event detected by NASA’s InSight on April 6, 2019, the 128th Martian day, or sol, of the mission. Three distinct kinds of sounds can be heard, all of them detected as ground vibrations by the spacecraft’s seismometer, called the Seismic Experiment for Interior Structure (SEIS): There’s noise from Martian wind; the seismic event itself; and the spacecraft’s robotic arm as it moves to take pictures.

Scientists predict a new solar cycle is about to begin and that it might be stronger than the last one

(11. April 2019)

The decline in sunspot activity through cycle 24 was worrisome to some space weather scientists in that it suggested a return to a lengthy “solar drought,” reminiscent of the Maunder Minimum period of 1645-1715. Records show the sun was essentially spotless for this lengthy period, coinciding with the “Little Ice Age” in Europe and tickling the interest of scientists to wonder whether there is a cause-and-effect relationship between solar behavior and Earth’s climate.

NASA Erased First Moonwalk Tapes, But Restores Copies

(17. Juli 2009) After a three-year search for a set of data tapes that promised to offer an improved view of the first moonwalk by Neil Armstrong and Buzz Aldrin 40 years ago this month, NASA revealed on Thursday that the tapes were more than likely erased years ago and reused. But the agency then unveiled the next best thing: restored footage based on their best broadcast quality tapes.

One giant blunder for mankind: how NASA lost moon pictures

(5. August 2005) THE heart-stopping moments when Neil Armstrong took his first tentative steps onto another world are defining images of the 20th century: grainy, fuzzy, unforgettable.

But just 37 years after Apollo 11, it is feared the magnetic tapes that recorded the first moon walk – beamed to the world via three tracking stations, including Parkes’s famous „Dish“ – have gone missing at NASA’s Goddard Space Centre in Maryland.

A desperate search has begun amid concerns the tapes will disintegrate to dust before they can be found.

Earth’s Oldest Known Rock Found on Moon – Scientists Explain How It Got There

The rock was among the samples discovered by the Apollo 14 crew. The Apollo missions brought back a whole bunch of rock samples, and scientists have been methodically analyzing them ever since.

NASA unveils new goals for Moon, Mars, including space privatization ​

(1.10.2018) These certainly mean more dollars headed toward research and development; while the original Apollo and other missions were government-funded and ultimately fell under the purview of the military (indeed, one of the primary stated goals of the Gemini and Apollo programs was to lessen the „Missile gap“ between the United States and the Soviet Union), this new concept relies heavily on private investment, corporate involvement and funding, and the eventual mining and financial rewards of „exploration and use“ of the lunar and Mars surfaces.

Soyuz Rocket’s Launch-Abort Close Call Highlights Poor Space-Policy Decisions (Op-Ed)

(16.10.2018) One of the cornerstones of the current space policy is to somehow „privatize“ or „commercialize“ the ISS by 2024-2025 and to use the „savings“ from that privatization to help fund the program. The idea of operating the ISS profitably is so preposterous that I don’t feel a need to comment further here. Besides, from where is the funding to come before 2024-2025?

What this look back shows is consistently poor policy decisions going back at least 14 years. What will happen to NASA and U.S. spaceflight in the coming years?
