The Origins Space Telescope will trace the history of our origins from the time dust and heavy elements permanently altered the cosmic landscape to present-day life. How did galaxies evolve from the earliest galactic systems to those found in the universe today? How do habitable planets form? How common are life-bearing worlds? To answer these alluring questions, Origins will operate at mid- and far-infrared wavelengths and offer powerful spectroscopic instruments and sensitivity three orders of magnitude better than that of Herschel, the largest telescope flown in space to date.
Origins was designed to minimize complexity. The telescope has a Spitzer-like architecture and requires very few deployments after launch. The cryo-thermal system design leverages JWST technology and experience. A combination of current-state-of-the-art cryocoolers and next-generation detector technology will enable Origins' natural background-limited sensitivity.
Same problem!! I also hosted my frontend on hosting, and even after adding it's domain in all possible configurations to the both "Authorized redirect urls" and "Authorized JS origins", I still see this error in the console. I even checked "origin" query param in the popup menu, and excluding coded slashes and colon it's the same as the one I added in the console. It looks like my changes in the console wasn't applied, and I have to wait for it, but I'm trying to solve it for couple of days now, and this is clearly not the case
The Origins of Life Initiative supports multi-disciplinary research aimed at revealing if life is abundant in the Universe. We seek to understand how the initial conditions on planets, including our own Earth and planets around other stars, dictated the origins of life and its subsequent evolution. Using this knowledge, it will eventually be possible to study the atmospheres of far distant planets for signs of life, including planets that might be Earth twins.

Select Subcommittee Chairman Brad Wenstrup opened the hearing by emphasizing how knowing the origin of the virus is essential to helping predict and prevent future pandemics, protecting health and national security, and preparing the United States for the future. He pledged that the Select Subcommittee will thoroughly, responsibly, and honestly investigate the origin of COVID-19.
Dr. Robert Redfield, former director of the U.S. Centers for Disease Control and Prevention (CDC), testified how science indicates COVID-19 infections were likely the result of an accidental lab leak in Wuhan. His conclusion is based on the biology of the virus itself and unusual actions in and around Wuhan in 2019, including gain-of-function research at the Wuhan Institute of Virology (WIV).
Nicholas Wade testified about the campaign to discredit the lab leak theory. He pointed out that scientists kept in line with the natural origin camp led by Drs. Fauci and Collins because of their dependence on government grants and that the media failed to challenge the forced narrative.
Subcommittee Chairman Dr. Wenstrup (R-Ohio.) asked witnesses whether it is critical to investigate the origin of COVID-19. All witnesses answered yes. Chairman Wenstrup also raised concern about gain-of-function research, which Dr. Redfield defined during the hearing as altering a pathogen to increase either transmissibility or pathogenicity.
Rep. Nicole Malliotakis (R-N.Y.) noted that after raising concerns to experts and the World Health Organization that COVID-19 may have originated in a lab in Wuhan, China, and urging Dr. Fauci to investigate the origins of the pandemic, Dr. Redfield was excluded from calls related to the origins of the pandemic.
Rep. Miller-Meeks (R-Iowa), who has expertise publishing in peer-reviewed scientific journals, asked why the scientific community dangerously suppressed evidence that COVID-19 may have originated from a lab.
Was it for personal financial gain? Was it to hide U.S. financial interest into the Wuhan Institute of Virology indirectly? Was it to suppress the revelation that there was perhaps gain-of-function research that had been prohibited in the United States? Or were they concerned that a conspiracy would develop that it was bioterrorism?
Oversight Committee Chairman James Comer (R-Ky.) warned that the media downplayed, discredited, and silenced voices of experts sounding the alarm that COVID-19 may have originated from a lab in Wuhan, China.
Each configuration can have one or more origins associated with it. Originconfigurations tell Media CDN how to connect to yourinfrastructure, when and how to fail over, retry, and time out, and what protocolto use when connecting.
Customers might see different offload rates depending on their cacheconfiguration, user load, workloads (such as live versus on-demand), userdistribution, and how much long-tail content (total corpus size) they serve tousers across regions.
Collapsed requests have both the client-facing request logged and the(collapsed) cache fill request logged. The leader of the collapsed session isused to make the origin fill request, which means that the origin sees theheaders (including the User-Agent) of only that client.
Media CDN uses HTTP/2 (h2) to connect to an origin by default.HTTP/2 and HTTPS both require a valid, publicly trusted TLS (SSL) certificate. Avalid certificate is one that is unexpired, signed by a public CertificateAuthority, and has a Subject Alternative Name matching the hostname sent to theorigin.
Any hostRewrite settings are ignored when using a Cloud Storagebucket as the origin because alternative host header values are not supportedby Cloud Storage buckets. The host header is automatically set based onthe bucket name.
For information about rewriting host headers for per-route configuration, seeConfigure service routes. For information about settingper-origin override actions, see Origin failover without redirect following.
Both timeouts include the time that the origin takes to return headers and to determine whether to use a failover or redirect. connectTimeout applies independently for each origin attempt, while maxAttemptsTimeout includes the time required to connect across all origin attempts, including failovers and redirects. Following a redirect counts as an additional attempt to connect to the origin, and counts toward the maxAttempts set for the configured origin.
When Media CDN encounters a non-redirect response, such as from a redirect or failover origin, the readTimeout and responseTimeout values apply. Redirected origins use the connectTimeout, readTimeout, and responseTimeout values configured for the EdgeCacheOrigin that encountered the redirect.
responseTimeout and readTimeout control how long a streamed response cantake. After Media CDN determines that it's going to use anupstream response, neither connectTimeout nor maxAttemptsTimeoutmatter. At this point, readTimeout and responseTimeout come into effect.
Media CDN makes at most four origin attempts across all origins,regardless of the maxAttempts set by each EdgeCacheOrigin.Media CDN uses the maxAttemptsTimeout value from the primaryEdgeCacheOrigin. The per-attempt timeout values (connectTimeout,readTimeout, and responseTimeout) are configured for the EdgeCacheOriginof each attempt.
The maximum amount of time Media CDN can take from starting the request to the origin until Media CDN determines whether the response is usable. Practically, connectTimeout covers the time starting with creating the request, then doing DNS lookups, then doing TLS handshakes, TCP/QUIC connection establishment, through getting the response headers that contain the HTTP status code.
The maximum time across all connection attempts to the origin, including failover origins, before returning an error to the client. An HTTP 504 is returned if the timeout is reached before a response is returned.
This setting defines the total duration for all origin connection attempts, including failover origins, in order to cap the total time clients have to wait for content to start streaming. Only the first maxAttemptsTimeout value is used, where the first is defined by the origin configured for the given route.
The maximum duration to wait between reads of a single HTTP response. The readTimeout is capped by the responseTimeout. All reads of the HTTP response must be completed by the deadline set by the responseTimeout. The timeout must be a value between 1 second and 30 seconds. If this timeout is reached before the response is complete, the response is truncated and logged.
Origin C matches requests to "/manifests/*, has a maxAttemptsTimeout valueof 10s, a maxAttempts value of 3, and failover_origin not configured. TheconnectTimeout value is at its default of 5s. Media CDNattempts to connect to Origin C up to three times, allowing up to 10 seconds(the maxAttemptsTimeout limit) to make a successful connection.
Media CDN supports origin retries, allowing unsuccessfulrequests to the origin to be retried. You can specify how many times thecurrent origin can be retried against before a failover origin (if configured)is attempted.
If Media CDN receives a status code matching any configuredretryConditions, such as an HTTP 404 Not Found or HTTP 429 Too ManyRequests error, and subsequent retry and failover origin requests continue tofail, an HTTP 502 Bad Gateway error is returned to the client after originattempts are exhausted.
