Liftoff for Cheops

ESA’s Cheops mission lifted off on a Soyuz-Fregat launcher from Europe’s Spaceport in Kourou, French Guiana, at 09:54:20 CET on 18 December on its exciting mission to characterise planets orbiting stars other than the Sun.

Signals from the spacecraft, received at the mission control centre based at INTA in Torrejón de Ardoz near Madrid, Spain, via the Troll ground tracking station at 12:43 CET confirmed that the launch was successful.

These sounds were recorded by connecting a 500 foot long antenna to the Mic input of my PC soundcard. This allows the soundcard to receive signals up to about 45 Khz if your soundcard is set to a 96000 hz sampling rate. Some of the sounds are from a nearby AM station and the others I'm not sure. Electrical disturbances in the air, like lightning or high voltage discharges, will also be picked up. Meteors or anything Ionizing in the upper atmosphere can also be picked up but they need to be close to the antenna.

Most of the photos seen here were taken by me. Some are the red sprites I captured over Hurricane Matthew and some are red sprites and gigantic jets over Tropical Storm Harvey. I also included some photos I found at the Gemini Observatory and the CFHT in Maunakea. I also added a couple of red sprite photos taken by the International Space Station.

The Detection of a Molecular Outflow in a Primeval Starburst Galaxy

Figure 1: Absorption profile of the two water transitions observed towards the far-infrared continuum emission of the distant starburst galaxy (SPT 0346-52).

Figure 2. Molecular outflow rate (Ṁ) as a function of star formation rate (SFR) for galaxies with detected molecular outflows. Outflows driven by AGNs are shown by diamonds, while those driven by starbursts are shown by star symbols. Each object is coloured according to its redshift. The range and average of best-fit outflow rates of our object (SPT 0346-52) are shown. The molecular outflow detected in this work is in the most powerful starburst. Additional data include both low-redshift (z~1.5-5.3) sources. A representative uncertainty for all low-redshift sources (±0.3 dex) is shown for one such source.

Using the Atacama Large Millimeter/submillimeter Array, a team led by scientists from the Kavli Institute have observed two water absorption lines towards a starburst galaxy (i.e., forming stars at a rate ~4000x faster than the Milky Way) in the early Universe, or about one billion years after the Big Bang, finding evidence for outflowing gas (Figure 1).

The distinct shape of these blueshifted water lines, in addition to the extremely hot and dense environments required for their detection, indicates that they originate from a massive nuclear outflow.

When the outflow rate and star formation rate of this object are compared to those of local galaxies and other high-redshift objects (see Figure 2), it is apparent that the outflow detected here is at the highest redshift and originates from the object with the highest star formation rate. However, the outflow rate is much less than the star formation rate, suggesting that this outflow does not represent a dominant form of mass loss in this system. Thus, the galaxy is likely undergoing a period of runaway star formation.

This work was led by Gareth Jones, a postdoctoral research associate at the Kavli Institute and the results has been published in Astronomy & Astrophysics Letters:

I not only captured the explosion but I also recorded the atmospheric disturbance due to the Ionization of the air. Instead of using a microphone I connected a 500 foot long wire to my PC soundcard. This allows me to pick up atmospheric sounds and frequencies up to about 45 Khz.

NASA’s X-59 Quiet Supersonic Research Aircraft Cleared for Final Assembly

NASA’s first large scale, piloted X-plane in more than three decades is cleared for final assembly and integration of its systems following a major project review by senior managers held Thursday at NASA Headquarters in Washington.

The management review, known as Key Decision Point-D (KDP-D), was the last programmatic hurdle for the X-59 Quiet SuperSonic Technology (QueSST) aircraft to clear before officials meet again in late 2020 to approve the airplane’s first flight in 2021.

“With the completion of KDP-D we’ve shown the project is on schedule, it’s well planned and on track. We have everything in place to continue this historic research mission for the nation’s air-traveling public,” said Bob Pearce, NASA’s associate administrator for Aeronautics.

The X-59 is shaped to reduce the loudness of a sonic boom reaching the ground to that of a gentle thump, if it is heard at all. It will be flown above select U.S. communities to generate data from sensors and people on the ground in order to gauge public perception. That data will help regulators establish new rules to enable commercial supersonic air travel over land.

Construction of the X-59, under a $247.5 million cost-plus-incentive-fee contract, is continuing at Lockheed Martin Aeronautics Company’s Skunk Works factory in Palmdale, California.

Three major work areas are actively set up for building the airplane’s main fuselage, wing and empennage. Final assembly and integration of the airplane’s systems – including an innovative cockpit eXternal Visibility System – is targeted for late 2020.

Management of the X-59 QueSST development and construction falls under the Low Boom Flight Demonstrator project, which is part of NASA’s Integrated Aviation Systems Program.

Back To Back Perseid Meteors with Audible Ping

These meteors were found to be early Perseid meteors. The audio ping was obtained by using a 500 foot long telephone wire connected to my PC soundcard. This allows me to capture atmospheric sounds that are either VLF frequencies or ionization in the air. In this case, it picked up the ionization in the upper atmosphere caused by the meteors.

This event was captured in Puerto Rico on July 22, 2019 at 4:46am local time (08:46 UTC).

Boeing Crew Ship Preps for Launch as Crew Studies Space Biology

ISS - Expedition 61 Mission patch.

December 16, 2019

Boeing is ramping up for the launch of its first commercial crew vehicle to the International Space Station this week. The Expedition 61 crew is preparing for the new U.S. crew ship’s arrival while working human research and space biology today.

Boeing is targeting 6:36 a.m. EST Friday, Dec. 20, for the launch of its first CST-100 Starliner crew ship to the orbiting lab. It will dock to the forward-facing port of the Harmony module on Dec. 21 and return to Earth on Dec. 28. This will be an uncrewed orbital flight test of Boeing’s new spaceship and sets the stage for launching crews once again from the United States.

Image above: Expedition 61 Flight Engineers Andrew Morgan and Christina Koch of NASA, ESA (European Space Agency) Commander Luca Parmitano and NASA Flight Engineer Jessica Meir pose for a portrait in the entryway into the cupola. Image Credit: NASA.

NASA Flight Engineer Christina Koch activated communications gear that will link up with the Boeing Starliner when it arrives Saturday. The C2V2 device (Common Communications for Visiting Vehicles) transmits telemetry from the approaching spacecraft to crew and ground controllers. The C2V2, used by the U.S. Dragon and Cygnus resupply ships, also enables an astronaut to remotely control a spacecraft if necessary.

ESA (European Space Agency) Commander Luca Parmitano and NASA Flight Engineer Andrew Morgan started Monday with hearing checks. The duo set up gear for the Acoustic Diagnostics study that measures hearing before, during and after a mission and assesses the noisy environment aboard the orbiting lab.

NASA astronaut Jessica Meir began her day on an exercise bike for a study measuring her aerobic and cardiovascular output. She then joined Koch in the afternoon feeding lab mice and cleaning their habitats.

Russian cosmonauts Alexander Skvortsov and Oleg Skripochka focused on life support and lab maintenance today. Skvortsov synchronized computers and cameras to station time and serviced an oxygen generator. Skripochka also checked out Russian laptop computers and radiation detection gear.

According to the star map, this could be a Southern Delta Aquarid meteor. I've captured many meteors at dawn but never a fireball. This one appeared just as the Sun was beginning to rise in the east at 5:35am local time (09:35 UTC).
