StratoCat joins "Buy me a coffee" for funding

October 4, 2021.- I've run this website in an "advertising free" basis for almost 16 years. However, to do that is not allways easy. Recently I was told about the Buy me a coffee initiative, and found that it could be a nice and easy way to get some support for the research I do.

Take a minute and learn how you can collaborate with this project.

Balloon launches database updated

October 1st, 2021.- New update to the database that form the core of StratoCat. Covering 74 years of worldwide activity with stratospheric balloons, the database offers detailed information of more than 14.800 balloon missions. This update includes a great amount of launches from NASA balloon program, Raven Aerostar and the latest flights of Project Loon before the closure of the project past January.

The road to the biggest jumps

So long time passed since 2012, when I've published the interactive timeline of the history of all the efforts that led to the succesful completion of Felix Baumgartner's jump under the Red Bull Stratos project. Now I've added more information, including the incredible history behind Alan Eustace and project Stratex.

    Six balloon launch campaigns in a nutshell

    Between June and October 2018, six launch campaigns of stratospheric balloons were performed worldwide. Twenty succesful balloon missions were made, for the benefit of astronomy, astrophysics, atmospheric sciences, STEM training of students and technology advance. The scientific effort involved three transatlantic balloon flights from Sweden to Canada, a long duration arctic balloon mission from Svalbard to Canada, two flights over Texas, five missions in Ontario and three in Alberta, Canada, eight launches over New Mexico, and two short duration missions in Sweden...

    SuperBIT flight or the dream of any balloon scientist

    Palestine, Texas.- Launched at first try, undisturbed flight at altitude by hours, an instrument working as expected, and then landing it with minor damage in an unpopulated zone but with a nearby road for an easy recovery, is what I call a picture perfect balloon mission. I am not referring to some ideal scenario taken from some training manual of any agency's balloon program, but what happened from beginning to end with the SuperBIT telescope flight launched a few days ago from Palestine, Texas...

    Transatlantic balloon launch campaign from Sweden to Canada

    Kiruna, Sweden.- The NASA balloon program returned to Sweden to perform a balloon launch campaign from the facilities of the European Space Range (ESRANGE), near Kiruna, very close to Arctic polar circle. The missions to be performed during May and June, will consist in trans-atlantic flights from Sweden to Canada with a mean duration of 4 to 5 days and the recovery in the Nunavut territory. This flight scheme was inaugurated by NASA in 2005...

    Japanese balloon launch campaign in Australia

    Alice Springs, Australia.- Dozens of surprised inhabitants watched on April 7, the slow drift in the clean autumn skies of a very brilliant star, wondering what it was. It was not of extraterretrial origin, but its mission was in some manner related to the deep realms of space.

    The silver orb that mesmerized the ocasional sighters was in fact a huge stratospheric balloon launched early in the morning that day from the Alice Springs Airport as part of a balloon launch campaign by the Japan Aerospace Exploration Agency (JAXA)...

    Antarctic balloon launch campaign ends without flights

    McMurdo Station, Antarctica.- The weather did it again. The Nemesis of NASA's balloon program during the campaigns developed last year, does not seem willing to resign its role in the new year that just started.

    After sixteen attempts performed from December 8th to January 14th, the team of scientists from Washington University in St. Louis and NASA's Goddard Space Flight Center in charge of the operation of the SuperTIGER instrument, finally communicated via social media that the campaign was called off. The instrument will be put in storage at McMurdo during winter to be hopefully launched next summer...

    PIPER flight closes NASA balloon launch campaign in New Mexico

    Fort Sumner, New Mexico.- 2017 will be remembered in the annals of NASA's scientific balloon program as a particularly problematic year.

    Following the loss of the EUSO-SPB balloon in the Pacific in May and the free-fall incident which ended with the destruction of the BETTII telescope in June, the agency's fall campaign held each year at the Scientific Balloon Flight Facility in Fort Sumner, New Mexico, came to an end with only two flights performed of the seven planned, after suffering the worst weather conditions in many years...

    Fort Sumner, New Mexico.- The first flight of NASA's Fall balloon launch campaign was performed yesterday, as mission 680N from the Scientific Balloon Flight Facility that the agency maintains inside the boundaries of the Fort Sumner Municipal Airport, in New Mexico.

    The purpose of the flight was to transport a series of experiments as part of the High Altitude Student Platform (HASP) program which every year since 2006 include up to twelve student payloads in a stratospheric balloon launched by NASA with flight durations of 15 to 20 hours...

    First images of the BETTII remains after the free-fall accident

    Palestine, Texas.- A few days ago, on the same facebook page where we learned about the unfortunated accident suffered by the Balloon Experimental Twin Telescope for Infrared Interferometry (BETTII) past June, were published the first public images of the debris of the instrument after experiencing a free-fall from an altitude of 135.000 ft.

    The images show nothing more than a pile of tubes, electronics, and bend metal parts of the instrument...

    BETTII twin interferometer destroyed in free fall incident over Texas

    Palestine, Texas.- The first balloon mission of the NASA summer balloon launch campaign being carried out from the Columbia Scientific Balloon Facility, located in the outskirts of the city of Palestine, Texas, ended in the worst way.

    Accordingly to an entry published a few hours after by the BETTII team on its facebook page and later by NASA on its website, at the end of the flight, the payload was separated from the balloon following the standard procedure, when due to yet unknown reasons, the instrument separated from the parachute and free fell from an altitude of 135.000 feet, in west Texas...

    NASA summer balloon campaign from Palestine base

    Palestine, Texas.- As long as the weather cooperates, while I'm writing this lines probably would be a rush of activity at the most famous NASA balloon base, the Columbia Scientific Balloon Facility, located in the outskirts of the city of Palestine, Texas.

    The activity is part of the Summer balloon launch campaign at the base, which in 2016 returned to the launch activity after a hiatus of near 9 years. This year's campaign will involve the launch of three payloads...

    GENETRIX spy balloon program data published in StratoCat

    After a six month work and a search that endured almost 10 years, I'm publishing today in StratoCat for the first time an extensive and comprehensive bulk of information about a secret program carried out by the US Air Force and other agencies to obtain strategic reconnaisance of the Soviet Union and their allies.

    GENETRIX, was a secret program started in 1950 and executed in 1956 by the United States Strategic Air Command (SAC) and other agencies, under the cover of a meteorological and scientific effort. However, the real objective was to obtain photographic reconnaissance of the Soviet Union using high resolution cameras transported by stratospheric balloons riding the jet stream...
