Video: 00:13:21 Satellites in orbit underpin our modern lives. They are used in many areas and disciplines, including space science, Earth observation, meteorology, climate research, telecommunication, navigation and human space exploration. However, as space activities have increased, a new and unexpected hazard has started to emerge: space debris.
If space debris – uncontrolled human-made objects such as spent upper stages of rockets and pieces of satellites – hits a satellite, it could cause serious damage, which can even end a mission (as has happened in the past). If debris crashes on Earth’s surface, it could potentially hit populated areas.
In this second video, Nicolas looks back on the first key steps taken at ESA to develop the Space Safety Programme, devoted to the detection, prevention and mitigation of threats originating from space. This includes not just space debris but also asteroids and space weather. The latter is an intense, occasional energetic storm of particles and material emitted by the Sun. Mitigating these hazards protects our planet, society and economically-important infrastructure on Earth and in orbit.
A key element for the forecasting and prevention of space weather is to observe the Sun from the side. Discover more in this second video of the ESA Masterclass with Nicolas Bobrinsky. With 35 years of experience at ESA, Nicolas Bobrinsky is the former Head of Ground Systems Engineering & Innovation Department. He initiated and further managed the Space Situational Awareness and later the ESA Space Safety Programme.
In four episodes of this new series of ESA Masterclass, Nicolas takes us through major events in his career at ESA, covering cornerstone missions, first attempts, overcoming technical challenges, leading diverse teams and solving the unexpected problems that are part of any space endeavour.

Video: 00:01:20 Satellites play a vital role in monitoring the rapid changes taking place in the Arctic. Tracking ice lost from the world’s glaciers, ice sheets and frozen land shows that Earth is losing ice at an accelerating rate.
Using information from ESA’s ERS, Envisat and CryoSat satellites as well as the Copernicus Sentinel-1 and Sentinel-2 missions, research led by Tom Slater of the University of Leeds, found that the rate at which Earth has lost ice has increased markedly within the past three decades. Currently, more than a trillion tonnes of ice is lost each year.
To put this into perspective, this is equivalent to an ice cube measuring 10x10x10 km over Oslo’s skyline. Putting it another way, the amount of ice loss globally is equivalent to 12 000 times the annual water use of the Norwegian capital.
The sooner Earth’s temperature is stabilised, the more manageable the impacts of ice loss will be.
Continuity in satellite data is the key to predicting future ice losses, and to assist in mitigating the threats posed by sea-level rise, shrinking high mountain glaciers and further climate feedbacks. The Copernicus Expansion missions, CRISTAL, CIMR and ROSE-L have been designed to fill the gaps in current Sentinel capabilities for comprehensive monitoring of changes in the global ice cover.

The realm of Unidentified Flying Objects (UFOs) has been steeped in secrecy and enigma for a long time, with one person emerging as an enigmatic figure in this field - Robert Bigelow. He is a billionaire aerospace entrepreneur who founded Bigelow Aerospace and has had associations with the United States government and its UFO-related projects for several decades.
During an interview with filmmaker James Fox, Bigelow brought up the topic of disclosure – the potential release of information about the existence of extraterrestrial life and their interactions with Earth.
Bigelow asserted that he had carried out extensive studies on the impact of disclosure on the global population. He claimed that the potential fallout would be comparable to the biggest scandals in human history multiplied by a million. According to Bigelow, the economy would crumble, and organized religion would be severely affected if the reality of extraterrestrial life was exposed.
But how about the origins of Alien and Human Races?
Some contact with aliens has been well documented and their messages have been shared. The Urantia Papers which give an incredibly detailed report on the social, political and religious structure of the universe, according to a number of different beings of the realm. These reports, or "papers" leave nothing to the imagination as they describe the various forms of life on different inhabited worlds, what they look like, what they eat and breathe and their ideas about God.
The Urantia Book (sometimes called The Urantia Papers or The Fifth Epochal Revelation) is a spiritual, philosophical, and religious book that originated in Chicago sometime between 1924 and 1955. The authorship remains a matter of debate.
The text introduces the word "Urantia" as the name of the planet Earth and states that its intent is to "present enlarged concepts and advanced truth." The book aims to unite religion, science, and philosophy. Its large amount of content on topics of interest to science is unique among documents said to have been received from celestial beings. Among other topics, the book discusses the origin and meaning of life, mankind's place in the universe, the history of the planet, the relationship between God and people, and the life of Jesus.
